1A Preliminary Study on Fluid Inclusions and Mineralization of Xitieshan Sedimentary-Exhalative (SEDEX) Lead-Zinc Deposit显示文摘Xitieshan 铅锌存款在 Qaidam 盆的北边缘被定位, Qinghai 省,中国,并且开发了一个完全的海洋的 sedimentary-exhalative 系统。我们形成矿石的液体的初步的学习证明在从代表管子外形的改变的 stockwork 岩石的石英的液体包括有大量温度和咸度。强烈液体活动是 exhalative 系统的管子外形的特征。在在代表发泄近似的外形的厚床的云石招待的 unstratified 矿石身体附近的碳酸盐的液体包括在尺寸大并且有对高温度中等。他们代表 unerupted sub-seafloor 液体活动。在改变的 stockwork 岩石和碳酸盐中的液体有类似的 H2O-NaCl-CO2 系统,两个都属于 sedimentary-exhalative 系统。液体从管子外形移居到 unstratified 矿石身体。液体沸腾引起 CO2 蒸汽和液体 H2O 的分离。当液体移居进 unconsolidated 时,象进液体的海水的某参与一样的厚床的大理石, CO2 的逃跑,减少的温度和压力与形成矿石的材料的高、低的咸度和免职导致液体的 unmixing。二纯粹的液体在 unconsolidated 碳酸盐被套住,形成矿石的材料在 unconsolidated 碳酸盐被扔形成 sedimentary-exhalative 类型 unstratified 矿石身体。unstratified 矿石身体的形成矿石的温度直到显示在有一个巨大的形成矿石的潜力的高温度它的深。WANG Lijuan ZHU Xinyou WANG Jingbin DENG Jiniu WANG Yuwang ZHU Heping 2008Acta Geologica Sinica(English Edition)2008,82,4:4
2Massive Sulphide Deposits Related to the Volcano-Passive Continental Margin in the Altay Region显示文摘The Devonian volcano-passive continental margin in southern Altay is a significant volcanogenic massive sulphide metallogenic belt. Acidic volcanism has been dominant on the inner side of the volcano-passive continental margin, i.e., near the old land, resulting in a Pb-Zn metallogenic sub-belt, in which the ore deposits are hosted by sedimentary rocks in volcanic series, as represented by the large Koktal Pb-Zn deposits. In the central part of the margin far away from the old land, bimodal volcanic formations are well developed, forming volcanics-hosted Cu-Zn metallogenic sub-belts, e.g., the large-scale Ashele Cu-Zn deposit. The Qiaoxiahala sub-belt on the outer side of the margin near the ocean ridge is located at the spreading central trough, where ophiolite suites are developed. This type of deposits is rich in gold and copper, similar to the Cyprus-type Fe-Cu-Au metallogenic sub-belt in metallogenic environment (represented by the Qiaoxiahala medium-scale Fe-Cu-Au deposit).
