In comparison with the First Conference on gold, the number of organizations and the number of reports increased significantly, as can be seen from the following table:

Major scientists and specialists in gold took an active part in the work of the Second Conference. In terms of the composition of the participants and the range of questions considered, the Second Conference was, in essence, an interdepartmental conference devoted to the study of gold deposits of Siberia, the Urals, the Far East, and Kazakhstan.

The work of the conference took place at plenary sessions and in four sectional meetings. At the plenary sessions (chairman F. N. Shakhov) 9 papers were heard; in Section I (“The connection of gold mineralization with magmatism and metamorphism”—chairman S. S. Il’enok) 20 papers were heard; in Section II (“Processes of ore formation”—chairman N. V. Petrovskaya) 26 papers were discussed; in Section III (“Geology of ore fields and deposits”—chairman P. F. Ivankin) 26 papers were heard; in Section IV (“Placers. Methods of prospecting and laboratory study of ores”—chairman D. S. Mikov) 24 papers were heard, i.e., 105 papers in all.

The work of the conference proceeded in a businesslike atmosphere; discussion of the papers was sufficiently active, with concrete and well-disposed criticism; on a number of questions sharp debates developed (the genesis of gold mineralization in conglomerates, the connection of mineralization with metamorphism, the young age of industrial mineralization of the Kuznetsk Alatau, etc.).

At the conference, theoretical problems of ore formation were discussed, as were the genetic connection of gold mineralization with the processes of magmatism and metamorphism, the regional metallogeny of gold, the genesis of gold-ore deposits of various formations and types, the regularities of localization of mineralization within ore fields and deposits, the geochemistry of gold, and also questions of methods of prospecting for and evaluating primary and placer deposits, the geology of placers, the study and analysis of gold-bearing ores, and many others.

The experience of scientific-research work and the practice of prospecting and exploration in gold-bearing regions and ore fields, as the results of the work of the Second Conference show, confirm the correctness of the main directions of research on the gold potential of Siberia outlined by the First Inter-University Conference.

Conferences and meetings on gold, with broad participation by scientific and production organizations, stimulated the development of work on the study of the gold potential of Siberia and on strengthening the raw-material base of the gold-mining industry. Over the past two years the scientific level of research has risen still more, the connection between scientific and production organizations has improved, and the range of questions being studied has expanded—

processes. The links between gold mineralization and the processes of magmatism and metamorphism are being successfully studied; the correctness has been confirmed of orienting the search for new promising types of mineralization (quartz-magnetite vein zones, conglomerates, etc.).

Geological institutions of Siberia are continuing extensive work on generalizing and systematizing materials, with the compilation of regional maps of gold content and forecasts. Geological-structural, petrographic, mineralogical, and geochemical study of ore fields under exploitation is being carried out more broadly and in greater depth. Certain successes have been achieved in studying the geology and regularities of the distribution of gold-bearing placers. Work of a methodological character has become more active. The conference notes with satisfaction that the complex of research methods used, including precise methods, is expanding increasingly.

The new factual materials and conclusions discussed at the Second Conference showed that the task of studying the raw-material base of the country’s gold-mining industry is being solved in a methodologically correct manner and at a modern scientific level.

The Conference notes the necessity of further strengthening research in a number of directions set forth in the reports and presentations of its participants, and also formulated in the resolutions of the First Conference.

1. It is necessary to strengthen prognostic-metallogenic studies for gold, setting as the goal the transition to the compilation of large-scale maps of ore nodes and districts on a geological and tectonic basis, especially near operating mining enterprises.

2. Of importance is the further deepening of studies on ore-bearing magmatic complexes and the determination of possibilities for using the entire diversity of forms of connection between gold mineralization and magmatic and metamorphic processes, which is important for creating the theoretical foundations of forecasts and for directing prospecting work.

3. Using modern methods for determining low gold contents (radioactivation analysis, the method of amalgam polarography with accumulation, etc.), it is necessary to expand work more broadly on the systematic study of disseminated gold content in sedimentary, volcanogenic-sedimentary, metamorphic, and magmatic formations, with the aim of establishing the primary sources of gold for various formational types of its deposits and the regularities of gold migration in the process of ore formation and in the subsequent period.

4. It is necessary to strengthen geological-structural and morphological studies of ore fields under development, with the aim of more fully revealing the regularities of localization of gold ores of various types.

5. Noting the fruitfulness of work on identifying and studying the endogenous and exogenous zonality of deposits and ore fields, the Conference emphasizes the necessity of strengthening these lines of research, which are important for substantiating prognostic estimates of gold mineralization, especially for evaluating the deep horizons of deposits.

6. The Conference emphasizes the urgency of detailed petrographic and mineralogical-geochemical studies, with the application of facies and formational analyses of magmatic, metamorphic, and ore formations. The further development is necessary of special mineralogical studies accompanied by the study of the composition and physical properties of ore-forming minerals, first of all objects of industrial interest—native gold; by the study of its typomorphic features characteristic of deposits of different genesis. The carrying out of such work will contribute to the solu-

... the solution of important genetic questions and the development of new prospecting and appraisal criteria.

1. The Conference draws geologists’ attention to the need to intensify studies of certain types of gold mineralization that are acquiring important economic significance: gold-bearing conglomerates of Precambrian and other formations, gold-bearing skarns and listvenites, quartz–magnetite vein zones, shear zones with disseminated and veinlet sulfide mineralization, and deposits of near-surface genesis in areas of young volcanism.

Special attention should be paid to the ore-controlling role of large tectonic structures that developed over long periods, especially in areas of tectonic activation.

1. Alongside the successes achieved in the geophysical study of gold-ore districts, there is a noticeable insufficiency in the use of geophysical methods in the practice of prospecting and exploration for various types of gold deposits. It is necessary to introduce geophysical methods more widely at all stages in the study of gold-ore districts and deposits, to strengthen work on summarizing the available results of geophysical investigations for the principal gold-ore districts, and to develop and introduce new progressive methods of ore geophysics.

2. In organizing prospecting for gold, the integrated application of various methods is expedient. The development and introduction of a complex of geochemical methods for gold prospecting should be strengthened. Work must be carried out toward improving and developing new effective prospecting methods, especially new methods for prospecting concealed mineralization and assessing the prospects of deep horizons of deposits.

Also deserving approval is the development of new highly sensitive methods for determining low (clarke) contents of gold in natural industrial types (the method of amalgam polarography with preconcentration, radioactivation analysis). The Conference recommends that production and scientific organizations carrying out geochemical investigations introduce these methods.

1. The Conference emphasizes the importance of further expanding the ties of production organizations with higher educational institutions and scientific institutions of Siberia, with the organization of contract-based work and the conduct of collective studies in creative collaboration. It is necessary to practice still more widely the conduct of joint scientific-research work to summarize materials from the exploration and exploitation of ore deposits.

2. The Conference draws the attention of the rector of the Tomsk Polytechnic Institute, the Ministry of Higher and Secondary Specialized Education of the RSFSR, and the Ministry of Geology of the USSR to the need to expand the laboratory of geology and geochemistry of gold at the Tomsk Polytechnic Institute, to strengthen its scientific-research base, and to transfer it from the category of laboratories administered on a voluntary basis to the category of problem-oriented state-budget laboratories.

3. The work of the permanent commission for the study of the gold-bearing potential of Siberia (at the Tomsk Polytechnic Institute) must be strengthened with regard to the further coordination and planning of joint research work, methodological consultations, the organization of exchange of experience among teams, periodic scientific conferences, and the publication of materials and proceedings on the gold of Siberia. The Conference approves the new composition of the commission (according to Appendix No. 1).

4. The permanent commission is instructed to appeal to the Minister of Geology of the USSR, Academician A. V. Sidorenko, and to the head of ...

of the Main Geological Administration of the Ministry of Non-Ferrous Metallurgy, A. S. Bogatyrev, with a request to assist in the most rapid publication of the proceedings of the Second Conference, in view of their great importance for increasing the effectiveness of prospecting and exploration work for gold.

1. For editing the proceedings of the Second Conference, approve a working editorial board composed as follows: N. I. Borodaevsky (TsNIGRI), B. D. Vasiliev—secretary (TPI), P. F. Ivankin (SNIIGGiMS), S. S. Ilyenok (TPI), A. F. Korobeinikov (TPI), A. M. Kuzmin (TPI), D. S. Mikov (TPI), N. V. Petrovskaya (IGEM, Academy of Sciences of the USSR), F. N. Shakhov—managing editor (Siberian Branch, Academy of Sciences of the USSR), G. V. Shubin (TPI).

2. The participants of the conference note with satisfaction the timeliness and expediency of convening the Second Conference in the city of Tomsk, the substantial work of the conference organizing committee, and the active participation of research staff of the Tomsk Polytechnic Institute in the preparation and conduct of the conference, and express their gratitude to them.

3. The standing commission shall determine the subject matter and the time for holding the Third Conference on the study of the gold-bearing potential of Siberia.
