摘要
塔河地区石炭系仅发育下石炭统巴楚组和卡拉沙依组。经研究 ,石炭系中共发育块状砂质砾岩相、板块交错层理含砾砂岩相、槽状交错层理含砾砂岩相、板状交错层理砂岩相等 11种沉积微相。石炭系中共识别出 4大沉积体系 :辫状河三角洲体系、三角洲体系、泻湖 -潮坪体系和碳酸岩台地体系。其中 ,辫状河三角洲体系最为发育 ,是石炭系的主要组成部分 ;碳酸岩台地体系发育最为局限 。
The Lower Carboniferous Bachu Formation and Karashayi Formation developed in Tahe Region could be divided into massive sandy conglomerate facies,platy cross bedded conglomeratic sandstone facies,trough cross bedded conglomeratic sandstone facies,platy cross bedded sandstone facies and 4 depositional systems such as braided river delta system,delta system,lagoon flat system and carbonate platform system.The braided river delta system developed well in the region,and plays the main part of the Carboniferous System;carbonate platform could only be found on the bottom of the Bachu Formation
