A mineralogical study of the inhalable particulate matter (PM_(10)) in Beijing urban air

中国海洋大学学报（英文版） 2017年第5期 747-756页

作者： LIU Jinqing YIN Ping ZHANG Yong SONG Hongying BI Shipu CAO Zhimin LIU Shanshan Key Laboratory of Marine Hydrocarbon Resources and Environmental Geology Ministry of Land and ResourcesQingdao Institute of Marine Geology Laboratory for Marine Mineral Resources Qingdao National Laboratory for Marine Science and Technology College of Marine Geo-Science Ocean University of China Geo-Engineering Investigation institute of Xiamen

Detrital minerals of 137 offshore and 22 river sediment samples collected from Qingdao coastal areas have been analyzed. Four mineral assemblage provinces can be classified by Q-mode cluster analysis. Factor analysis identifies two major factors that account for the total variability in most common minerals: 1) based on the relationship of quartz, hornblende, actinolite, micas, and authigenic pyrite, 41.55% of the variability is related to sediment sources; 2) based on the relationship of epidote, garnet, sphere, and ilmenite, 23.21% can be related to strong hydrodynamic conditions that control transport and sedimentation. By comparing mineral compositions of river waters in the study area, the following four mineral provenances can be identified. The Qingdao-Laoshan nearshore area has a quartz-feldspar-epidote-hornblende-limenite-limonite-sphene assemblage, which is largely attributed to relict sediment and coastal erosion. The Jimo-Haiyang nearshore area has a quartz-feldspar-hornblende-epidote-limonite-mica-actinolite assemblage, derived largely from the Wulong River and Rushan River, and is also affected by the Huanghe River, while the Qianliyan Island area in the deeper offshore area separated by a mud belt has a similar assemblage. The Haiyang-Rushan nearshore area has a quartz-feldspar-hornblende-epidote-micas-limonite assemblage, indicating multiple sources from the Rushan River, the Wulong River, the Huanghe River, and coastal erosion. The central area, located in an eddy center, has a mica-authigenic pyrite-hornblende-quartz-feldspar assemblage, indicating multiple sources dominated by Huanghe River distal sediments.

大量的同位素年代学证据表明（古）阿尔金断裂带可能形成于三叠纪，后又经历了侏罗纪、白垩纪的强烈左旋走滑活动，自印度板块与欧亚大陆碰撞后阿尔金断裂再次活动。主要的走滑活动发生在：（1）245～220Ma；（2）180～140Ma；（3）120～100Ma；（4）90～80Ma；（5）60～45Ma（6）渐新世至中新世；（7）上新世至更新世以及（8）全新世。沿阿尔金断裂带，伴随左旋走滑活动形成一系列的逆冲断裂和正断裂，反映走滑过程中伴随隆升作用的存在，并且形成自北向南包括祁连山、大雪山、党河南山、柴北缘山、祁漫塔格山和昆仑山，表明阿尔金断裂带制约着青藏高原北部的生长和隆升。阿尔金断裂带东、西两端的白垩纪和新生代火山活动是断裂走滑活动的响应。

日本富山县境内的中田浦滑坡剖面中产出以立方体为主要晶形的微小黄铁矿颗粒,它们多沿滑带土中的细裂缝分布。黄铁矿的产出状况、晶体形态以及滑带土的岩矿和地球化学特征均显示这些黄铁矿是滑带岩石粘土化作用过程的伴生产物,揭示滑带内的还原性氧化还原条件,它们总体受滑带的发生和发展所控制。因此,滑带土中的次生黄铁矿对于滑带土的形成具有特别的指相意义,有可能作为备选指标用来判断滑带的产生历史和发展进程,从而估计滑坡的发展演化。
