| Summary: | A review of foreign and Russian publications on gold-bearing Witwatersrand conglomerates dealing with investigations of sulfur isotopic composition of shingle-like formations of pyrites, that often contain gold, and of oxygen isotopic composition of quartz shingles, and carbon isotopic composition of host rocks, has been presented. In line with the development of isotopic investigations methods the values diapason of δ34S has been shown to essentially widen. However, the task of determination of the source of gold has not been solvedyet. Investigations of δ18O help to determine the fact of difference of the sources of gold and uranium. The presence of photosynthesis during Archean era has been confirmedas the source of oxygen in atmosphere. |
