| Abstract: | In the last decate O,C isotopes was applied to solving the genesis of Baiyan Obo H8 dolomite. Sample analysis shows that its values differ either from the typical sedimentary carbonate rock or from the typical magmatic carbonatite. Therefore, arguements are kept among geologists who once worked at Baiyan Obo ore deposit. Summed up three view points can be distinquished i.e. sedimentary carbonate rock, magmatic carbonatite and carbonate rock formed by 1:1 mixation of marine material and deepsourced material.Samples are collected by the author from controversial points along 32 line and 21 line. O,C isotope analysis is similar to that of limestone in the north of Kuangou Fracture so the author argue that H8 dolomite is originaly sedimentary carbonate rock. |
