新疆托里达尔布特断裂带北侧地层前人建立了下石炭统包古图组和上石炭统太勒古拉组，其地层归属北准噶尔地层分区玛依力地层小区。本次通过沉积岩剖面实测，依据地层资料、岩石特征，在该地区对比认定前人对这里的地层划分顺序有误。确定包古图组划归于下石炭统。包古图组主要为一套深海―半深海相的灰、灰黑色薄层状凝灰质粉砂岩、凝灰质泥岩，与灰绿色、灰色薄层状沉凝灰岩不均匀互层。主要岩性有含粉砂细粒岩屑砂岩、凝灰质砂岩、含粉砂泥质硅质岩、硅质岩、沉凝灰岩等。整体环境比较平静稳定，应为深海—半深海相沉积。太勒古拉组主要为灰、灰绿、紫红色玄武岩、安山岩、细粒凝灰岩、晶屑沉凝灰岩、火山灰沉凝灰岩、凝灰质粉砂岩、凝灰质粉砂质泥岩不均匀互层，夹碧玉岩、安山玢岩及长石砂岩、粉砂岩。分析应为还原环境下，有间歇性火山喷发的深海沉积环境。

Torricelli Daerbute fault zone north of Xinjiang formation predecessors established the Lower Carboniferous package Couto Group and the Commission on the Carboniferous too Le Dracula group, with the attribution of North Junggar formation formation of the district Mayi formation area. The profiles measured by sedimentary rock, based on formation, rock characteristics, in the region compared to their predecessors here that the formation of the order is wrong. Ancient map packets identified in the group was placed under the Lower Carboniferous. Bao ancient group plans for a major deep-sea - half of the deep gray and gray-black TLC tuffaceous siltstone, shale tuffaceous, with gray green, with thin gray-tuff interbedded uneven. Lithologic main debris containing fine sand silt, tuffaceous sandstone, with silt, mud cherts, cherts, such as Shen tuff. The overall environment is relatively calm and stable, for deep-sea - a half deep-sea sediments. Le Dracula is the main group for the ash, glaucum, purplish red basalt and andesite, fine-grained tuff, crystal-tuff debris, ash-tuff, tuffaceous siltstone, tuffaceous silty mudstone uneven beds, rocks folder jasper , Ansan porphyrite and long-sandstone and siltstone. Analysis should be the reinstatement of the environment, there are intermittent eruption of deep-sea sediment environment.
Key words: Pack ancient map; too Le Dracula groups: sedimentary environment; Xinjiang Torricelli; Daerbute fault
Key words: Pack ancient map; too Le Dracula groups: sedimentary environment; Xinjiang Torricelli; Daerbute fault
