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,仅在巴楚组底部见到。

关键词: 微相, 沉积体系, 石炭系, 塔河地区

Abstract:

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.

Key words: microfacies, depositional system, Carboniferous System, Tahe Region
