Abstract
Based on comprehensive analysis of primary logging data of buried ultrabasic alkali rock mass from verifying abnormality 40years before, igneous-carbonatite rock mass has been found, which was determinated to be the first typical ultrabasicrock -alkali rock-carbonatite rock trinity complex. The ultrabasic rock was multi-rhythmic bedded rock formation. there were 9 phosphate ore bed have been found with total thickness 68.25m and P2O5 4%~12.6%, which has been a large medium grade deposit. There are many same or similar features between Mashenqiao complex and Fanshan complex with exceptionally large comparability. Both of them awere found through aeromagnetic anomaly , their adjacent rock were mesoproterozoic Jixian system dolomite , the occurrence structure was Yanshan fold belt and both were multi-rhythmic bedded rock formation formed in indo-Chinese epoch, which produced large-ultra large apatite deposit. This is the unique feature of"Fanshan type".关键词
