Geological analysis and FT dating of the large-scale risht-lateral strike-slip movement of the Red River fault zone

Tectonically,the large-scale right-lateral strike-slip movement along the Red River fault zone is characterized at its late phase with the southeastward extension and deformation of the Northwestern Yunnan normal fault depression on its northern segment,and the dextral shear displacement on its central-southern segment.Research of the relations between stratum deformation and fault movement on the typical fault segments,such as Jianchuan,southeast Midu,Yuanjiang River,Yuanyang,etc.since the Miocene Epoch shows that there are two times dextral faulting dominated by normal shearing occurring along the Red River fault zone since the Miocene Epoch.The fission track dating (abbreviated to FT dating,the same below) is conducted on apatite samples collected from the above fault segments and relating to these movements.Based on the measured single grain's age and the confined track length,we choose the Laslet annealing model to retrieve the thermal history of the samples,and the results show that the fault zone experienced two times obvious shear displacement,one in 5.5 ±1.5 MaBP and the other in 2.1±0.8 MaBP.The central-southern segment sees two intensive uplifts of mountain mass in the Yuanjiang River-Yuanyang region at 3.6-3.8 MaBP and 1.6-2.3 MaBP,which correspond to the above-mentioned two dextral normal displacement events since the late Miocene Epoch.

西藏土则雪山铜多金属矿带地质特征

对西藏昆仑山南坡1∶20万化探工作中圈出的土则雪山HS16综合异常查证中,发现宽850 m,长约4 km,由8个铜、铜锌、铜铅锌和2个铜矿化体组成的大型铜多金属矿带,其矿床成因类型为兼具沉积砂岩型铜矿和中低温热液型多金属矿床的沉积改造型矿床.该调查区铜的找矿潜力极大,具备有发现矿田级铜矿产的前提.作为铜矿的伴生,共生银、铅、锌矿也具有相当的找矿潜力.     

河南省桐柏银洞岭银矿床地质地球化学特征

银洞岭银矿床属变质碎屑岩型银(金)矿床, 其成矿元素含量变化与歪头山岩组地层层序、岩石类型密切相关, 歪头山岩组下部变粒岩、云母石英片岩Ag含量相对较高, 成为银矿体的直接赋矿围岩;蚀变作用导致成矿元素显著带入, 而对稀土元素的迁移影响不大;成矿热液的运移以渗流作用为主、渗透作用为辅;通过对银洞岭银矿床地质地球化学评价标志的建立, 为该类型矿床的普查评价起到借鉴作用。     

鞍山小岭子花岗岩地球化学及锆石SHRIMP年代学

鞍山小岭子花岗岩岩浆锆石离子探针年龄为130.2±2.7Ma,形成于早白垩世。小岭子花岗岩高SiO2、Na2O K2O、TFeO/MgO,富集轻稀土元素和高场强元素Zr、Nb、Y,低CaO、Ba、Sr,地球化学组成与该区大范围分布的千山花岗岩十分相似,具A型花岗岩特征,其形成与古太平洋板块俯冲至中国大陆东部之下引起的拉张有关。
