长江口地区绿色颗粒的矿物学研究

本文对长江下游河道、长江口现代沉积区、口外残留砂沉积区及大陆架现代沉积区表层沉积物中的绿色颗粒进行了系统的矿物学研究。特别运用透射间和能谱分析对其内部超微结构、单晶结构和单晶化学组成进行了研究。长江口地区的绿色颗粒从宏观形态上可分为三类：颗粒状、书页状和生物状，不同的形态者，其形成机制基本相同，只是微晶聚集的微空间环境不同。绿色颗粒的颜色和成熟度有较密切的关系，颜色愈深，K和Fe含量愈高。其成熟度也愈高，K2O含量为3－7％，仅少数可达8.5％。绿色颗粒主要矿物成分为海绿石、鲕绿泥石、磁绿泥石和蒙4皂石。其中以海绿石为主，因此是一种复合型绿色颗粒。不同形态及不同沉积亚环境中绿色颗粒的矿物成分并无太大差别。

Fouling of floating plastic debris under Biscayne Bay exposure conditions

Six plastic/rubber materials commonly encountered in marine debris and beach litter were studied under Biscayne Bay (Florida, USA) exposure conditions to determine the effect of fouling on buoyancy. Studies under restricted floating, and restricted submerged exposure conditions suggest that most plastic samples undergo fouling to an extent to cause the sample to be negatively buoyant in sea water. Rapid defouling of the submerged fouled samples was observed. The findings suggest that free-floating plastics at sea may, under certain conditions, undergo fouling-induced sinking followed by resurfacing as floating debris.

符竹溪地区化探找金（锑）研究及地质效果

本文研究了符竹溪金－锑矿床微量元素地球化学特征，对矿区岩、矿石微量元素进行了相关分析，筛选出对符竹溪地区金、锑矿有指示意义的Ａｕ，Ｓｂ，Ａｓ，Ｍｏ，Ｗ，Ｈｇ，Ｐｂ，Ａｇ，Ｔｌ，Ｂｉ等１０个指示元素。经分析对比，确定其实用性指示元素为Ａｕ，Ｓｂ，Ａｓ，Ｍｏ，Ｂｉ，Ｈｇ。利用这些元素的轴向分带规律及比值指标对该矿床深部进行了成矿预测，并已由探矿工程证实，见到了金品位高达４４×１０（－６）的矿体，因而扭转了该矿山矿石资源面临枯竭的局面，经济效益显著。同时，对整个符竹溪地区，即矿床边部及外围作了化探选区，选出了３个远景地段：矿床南部竹叶山地段、外围杨家冲地段和田庄湾地段。     

北京密云麻粒岩相区变质作用演化及PTt轨迹的研究

北京密云麻粒岩相区在早前寒武纪时期主要经历了两期变质作用。每期变质作用又可划分为三个连续的变质阶段，峰期阶段的Ｐ－Ｔ条件均达到了麻粒岩相．第一期变质作用约结束于２５００Ｍａ，具有与造山带相似的顺时针ＰＴｔ轨迹，峰期阶段Ｔ为８００～９００℃，Ｐ＝０．９８～１．０２ＧＰａ，这种轨迹主要与早期平卧褶皱和推覆构造使地壳大幅度增厚有密切关系。第二期变质作用约发生在１８００Ｍａ，ＰＴｔ轨迹为具近等压加热（ＩＢＨ）特点的顺时针轨迹，峰期阶段Ｔ为７６０～８１０℃，Ｐ为０．９６～１．０４ＧＰａ，这种轨迹与大陆地壳的拉伸作用有密切关系。     

Lithofacies features and mechanism of formation of “Zihe-type” time- and strata-bound iron ore deposits in central Shandong province

The Lower Palaeozoic system is a series of iron-bearing rocks consisting mainly of shallow sea-fades carbonates. On the basis of microfacies analysis of the carbonate rocks, the Lower Palaeozoic sedimentary sea basin is divided into two broad sedimentary-tectonic regions of four sedimentary facies and eight subfacies. The original iron-rich carbonates were deposited in saltlakes, lagoons, etc. of the restricted basins. Over the long geological history, the original iron formations were reconstructed to various extents by late tectonic processes. Geological observations and studies on the equilibrium mechanism of oxygen/sulfur isotopic fractionation and the composition and temperature of fluid inclusions in the minerals indicate that thermal brines played an important role in reworking of the original iron-rich carbonate rocks, which led to the formation of sedimentary-reworked strata-bound ore deposit.
