新疆哈拉奇区域地质矿产调查新成果和主要进展
|
摘要
简要概述了新疆哈拉奇地区区域地质矿产调查过程中取得的新成果和主要进展。新建晚石炭世—早二叠世碳酸盐台地深水斜坡相的哈拉奇组;在石炭系—二叠系中共识别出4个带和1个珊瑚组合;在志留系中识别出笔石组合带;在石炭纪别根他乌组中发现多套古岩溶角砾岩层,在哈拉奇组中发现深水重力流沉积;识别厘定出石炭系/泥盆系和志留系/奥陶系2个平行不整合;依据不整合面划分2个构造层,并识别出3期区域性褶皱构造;划分出6个区域磁异常,4个高磁异常,并进行了查证和解译;圈定水系沉积物综合异常14处;探索性地开发针对数字化填图系统的Dliner数字化整饰平台。
This paper presents a brief overview of the latest achievements and major progress in the regional geological exploration and mineral resources survey of Karaqi area, which has been the first regional geological exploring and mineral surveying project since the transformation of the army's task. This project party established a new formation named Karaqi Formation comprising deepwater slope facies of carbonate platform between Late Carboniferous and Early Permian. The authors discovered four fusulinids belts and one coral combination in Carboniferous-Permian strata and one graptolite assemblage zone in Silurian strata. Paleokarst breccia layer was found for the first time in Biegentawu Formation and deepwater gravity flow deposits were detected in Karaqi Formation. Two parallel unconformities were recognized: one is in Devonian-Carboniferous, and the other is in Ordovician-Silurian. Three structural layers were detected on the basis of unconformable surface and two regional fold structures were recognized. Six regional magnetic fields and four high magnetic anomalies were delineated. In addition, the authors checked and interpreted these findings. 14 stream sediment integrated anomalies were delineated. The Dliner digital finishing platform was developed for the digital mapping system.
