缅甸睡宝盆地始新统重矿物组合与物源分析

据钻井A岩心薄片鉴定和重矿物资料分析,通过观察碎屑组分并计算其相对百分含量和分析重矿物指数特征,认为睡宝盆地始新世沉积物受到火山点物源的影响较少,主要来自东边掸邦高原方向的碎屑岩,具有近距离搬运的沉积特点,该区母岩岩性为云母片岩和云母石英片岩以及极少量的中性-酸性浅成岩浆岩。

Heavy Mineral Assemblage and Provenance Analysis of Eocene in Shwebo Basin,Myanmar

Based on the thin-section identification and the heavy mineral analysis,including the clastic component observation and relative percent content estimation as well as the ZTR index feature,it is suggested that the sediments(clastic rocks) of the Eocene in Shwebo basin in Myanmar are seldom affected by the volcanic facies provenance from Shan plateau in eastern Shwebo basin,which are characterized by a short-distance transportation.Based on the types of clastics and heavy mineral associations,the parent rock...
