仁达铜金矿床位于三江弧盆系的治多-江达-维西-绿春陆缘弧带内,矿区出露的地层主要为上三叠统地层公也弄组(T3g),岩性主要为结晶灰岩、生物碎屑灰岩;矿区出露的侵入岩主要为晚三叠世的花岗岩和早-中侏罗世的二长花岗岩。该矿床受地层、岩性及构造破碎带的控制,其中公也弄组(T3g)是该矿床的含矿地层,矿体主要产于与岩体接触的破碎带内。本文通过介绍了区域地质背景、矿区地质特征及成矿地质作用,初步讨论了仁达铜金矿的成因,认为该矿床属于矽卡岩型矿床。  相似文献

新疆祁漫塔格地区成矿地质条件优越,找矿潜力巨大,是新疆十大重要找矿远景区之一,维宝铅锌矿床是本世纪初新发现的产于蓟县系狼牙山组碎屑岩碳酸盐岩建造中的铅锌矿床。文章通过对维宝铅锌矿西矿区成矿地质特征的分析,认为该矿区主要受地层、岩性以及岩浆作用控制,矿床成因可能为与印支期岩浆作用有关的层控矽卡岩型矿床,该区矿体埋深较大,应综合分析地物化资料进行深部找矿。  相似文献

矿区位于柴达木-祁连板块南祁连早古生代褶皱带的西段,阿尔金东段成矿带,成矿地质条件优越。出露地层为下元古界野马南山岩群,构造以断层为主,岩浆岩发育,岩性为花岗斑岩、花岗闪长岩等,共圈综合异常两个Ht-1、Ht-2,异常总体分布呈带状。石块地金矿,赋矿岩性为花岗斑岩,矿床受岩体、构造控矿明显,属中温热液型金矿床。矿区圈定出9条金矿体,矿体总体变化趋势是,由地表到深部变薄乃至尖灭后又出现,呈膨大收缩状。构造控矿、化探异常、赋矿岩性、矿化蚀变均可作为该区域金矿找矿标志,研究结果为该地区同类矿床勘查提供一定的参考。  相似文献

Many of the links of religiousness with health, well-being, and social behavior may be due to religion's influences on self-control or self-regulation. Using Carver and Scheier's (1998) theory of self-regulation as a framework for organizing the empirical research, the authors review evidence relevant to 6 propositions: (a) that religion can promote self-control; (b) that religion influences how goals are selected, pursued, and organized; (c) that religion facilitates self-monitoring; (d) that religion fosters the development of self-regulatory strength; (e) that religion prescribes and fosters proficiency in a suite of self-regulatory behaviors; and (f) that some of religion's influences on health, well-being, and social behavior may result from religion's influences on self-control and self-regulation. The authors conclude with suggestions for future research. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

The relations of teachers' and parents' reports of children's shyness (i.e., social inhibition) at ages 6-8, 8-10, and 10-12 years to dispositional regulation, emotionality, and coping were examined. Shyness was positively related to internalizing negative emotion, coping by doing nothing, and, for parent-rated shyness, behavioral inhibition/nonimpulsivity, attention focusing, and avoidant coping; it was negatively related to positive emotionality, instrumental coping, seeking support from teachers (at younger ages), and for teacher-rated shyness, attentional control. Often prediction held over several years and/or across reporters. Parent-reported internalizing negative emotion at age 4-6 predicted shyness at ages 6-8 and 8-10, but primarily for children low in attention shifting. Teacher-rated shyness was related to low social status; parent-rated shyness correlated with boys' adult-rated social status at age 4-6 and with style of social interaction, particularly for girls. The relation between parent- and teacher-reported shyness decreased with age. The overall pattern of findings was partially consistent with the conclusion that parent-rated shyness reflected primarily social wariness with unfamiliar people (i.e., temperamental shyness), whereas teacher-rated shyness tapped social inhibition due to social evaluative concerns.  相似文献

Because of the small size of their genome, viral genes have been forerunners in helping us understand gene expression. It is also because of their small size that viruses have elaborated the amazing variety of strategies that enables them to produce all the proteins they require for their multiplication. As a consequence, many of the strategies of expression known to occur in cell systems were first demonstrated in viruses. The aim of this review is to highlight the contribution of viruses to our knowledge of cell processes.  相似文献

A major and well-recognized difficulty in estimating the effects of education on earnings is that the more educated are likely to be more able, irrespective of education. If ability also determines earnings and is not controlled, ordinary least squares will yield biased estimates of the education coefficient. In this study, we use data on identical twins to control for differences in ability that arise from genetic endowments and family environment. Not controlling for genetics and family environment may cause a large bias, up to two-thirds of the noncontrolled coefficient.  相似文献
