The following conclusions have been drawn:(1) According their field and petrologic characteristics and building upon previous works, Late Mesozoic and Cenozoic mafic dikes form Jiangxi province are complex in rock associations which are compose of lamprophyre and gabbro-diabase and diabase and diabase-porphyrite, are mainly distributed into three north-north-eastern strike belt including Xingzi-Shanggao-Pingxiang and Dexing-Yujiang-Xiangshan-Jian-Shangyou and Caotaobei-Dajishan.
本论文选择了江西省晚中生代以来的基性岩脉为研究对象,运用矿物学、元素和同位素地球化学及K-Ar测年等研究方法,首次较为系统地研究了江西省晚中生代以来的基性岩脉、与地壳拉张有关的基性侵入岩体的地质地球化学特征,并利用对其形成时代、源区性质的研究来探讨中国东南部地壳拉张期次、地幔性质等地球动力学背景中的关键性问题。

By analyzing in detail the structural evolutionary history, from Mesozoic to Cenozoic, of different rift belts in western, northern, central and eastern Africa, the authors think that the Mellit area was on the northwestern shoulder of the South Sudan Rift. The rotation of the Mellit block toward northwest was the outward rotation of the northwestern shoulder of the South Sudan Rift during the rifting phase, and the rotation toward southeast was the inward rotation of the rift shoulder during the post-rift thermal sag episode.
经过详细分析非洲大陆西部、北部、中部和东部中新生代裂谷带的构造演化史后发现:Mellit地块实际上位于南苏丹裂谷带的西北裂谷肩上,该地块自晚白垩世初期至中新世初期,向NW方向倾斜是南苏丹裂谷带于裂谷化阶段造成的裂谷肩块体的向外旋转;该地块自中新世以来向SE方向倾斜是南苏丹裂谷带在后裂谷热沉降阶段造成的裂谷肩块体的向内旋转。

By above research, the following results are obtained.(1)The extracting module of aero-radioactive thematic information is integrated with ENVI, the remote sensing image processing software;(2) Based on the IDL, the computer program modules extracting following uranium thematic information have been developed, including initial uranium contents, active uranium contents, uranium migration coefficient, uranium information strengthen, uranium D-value and variance Ratio etc, al. Some of kalium special information extracting modules are also developed;(3)Based on the IDL, the aero-radioactivity information multi-parameter focus analysis module is developed;(4) It is proposed that a lots of phenomenon of uranium immigrating exist in Keping-Kuche are in the Neocene period. Because of the uranium pre-enrichment, the areas with high uranium content were formed in Neozoic and Quaternary. The above migration uranium are also the abundant source for uranium ore-forming in favorable strata of Mesozoic and Cenozoic system;(5)There are obvious uranium immigrating and enrichment in Eastern Portion of Keping Block Uplift, Yinate-Laolongjiang, and Qidaoban-KuChe.
通过上述研究,取得了如下成果:(1)实现了航放专题信息提取模块与ENVI遥感图像处理软件的无缝集成;(2)基于IDL语言开发了初始铀含量、活性铀含量、铀迁移系数、铀信息增强、铀差值方差比等航放铀专题信息,钾专题信息提取处理程序;(3)基于IDL语言开发了航放信息多参数聚焦分析处理程序;(4)发现柯坪-库车地区在晚第三纪开始出现了大量的铀迁移富集现象,不仅使上第三系、第四系沉积时因铀的预富集而形成铀含量高场区,而且也为研究区中新生代有利目的层的铀成矿提供了铀源条件;(5)研究认为,研究区柯坪断隆东段,英阿特-老龙江,七道班-库车等三个区块存在明显的铀迁入富集。

During the Cenozoic, the evolution of the sag might be divided into three stages: during the Eocene, because of regional extension effect of the NW-SE-striking, it was a ramp depression controlled by the Cangdong fault; during the Oligocene, it might have subjected to the combined effects of the NW-SE-striking regional extension and the dextral slipping of the NNE-striking deep fracture zone; during the Neocene and the Quaternary, though the regional extension had mainly stopped, the dextral slipping continued. Inside the slip zone, the local, SN-striking extension related to the dextral slipping became more and more apparent.
新生代演化分为3个时期:NW-SE向区域伸展作用,凹陷是一个由沧东断层控制的断坡凹陷;渐新世,凹陷受NW-SE区域伸展和NNE向深断裂带右旋走滑的共同作用;晚第三纪到第四纪,区域伸展作用基本停止,走滑作用仍在继续,由走滑作用导致的SN向局部伸展作用显得更加突出。
