Abstract : the genesis of keketale lead - zinc deposit is discussed by means of its geological characters and geochemical characters , providing the basis for sulfide type lead - zinc deposit 文摘:通过可可塔勒铅锌矿床地质特征及地球化学特征的研究,探讨可可塔勒铅锌矿床的成因,为寻找硫化物型铅锌矿提供了依据。
Based on observation of many polished and thin sections and analyses of electron microprobe , the author suggests that dispersed elements in both the tianbaoshan and the daliangzi deposits occur as isomorphism 大量光、薄片观察和电子探针分析表明,天宝山、大梁子铅锌矿床中分散元素主要以类质同象形式存在。
The paper discusses the deep tectonic setting of yinshan lead - zinc deposit and emphaticly studies geological features of two fault belt and relationships between deep structures and mineralization 本文论述了银山铅锌矿床形成的深部构造背景,着重研究了桐柏?桐城断裂带、商城?麻城断裂带的地质特征及其与成矿作用的关系。
The tianbaoshan and daliangzi pb - zn deposits , strictly controlled by " formations , phases and structures " , are typical mvt pb - zn deposits . they also belong to the epigenetic hydrothermal strata - bound deposit 天宝山、大梁子矿床严格受“层、相、位”的控制,属后生热液层控矿床,也是典型的密西西比河谷型铅锌矿床。
The model holds that the metallogenic environment of the lf type is structural reductive space whereas that of the hf type reflects entirely characteristics of sedimentary minerallization , with no evidence of tectonic minerallization 模式表明,贫铁型矿床的成矿环境为相对封闭还原的构造空间;富铁型矿床完整地反映了该类型铅锌矿床沉积成矿特点显著,而断裂等构造对成矿的直接影响相对不显著。
A comparison of the prospecting model of the hf type with the prediction model of the vms type reveals that their thermal dynamic mechanisms are different : the former is related to basic - ultrabasic rock intrusion , while the latter to acidic rock intrusion 与白银铜矿区域地球化学预测模式相比较,富铁型铅锌矿床中除铁族元素指示基性超基性岩侵入事件外,其他元素均大致相似,两大类矿床形成的初始热动力条件不同。
Thermal deposits mainly formed during middle - late yanshanian age , related to extension structure , with main mineralization in qingfeng competent deformation zone , western shennongjia fault arch , northern huangling fault arch , xianfeng anticline of enshi platforman fold bundle 热液型铅锌矿床主要形成燕山中晚期,与滑脱拆离构造密切相关,矿化主要集中于青峰强变形带、神农架断穹西部、黄陵断穹北部、恩施褶皱束咸丰背斜、长阳褶皱束走马坪背斜中。
Huize pb - zn - ge - cd deposit is a typical ore deposit occurred in sichuan - yunnan - guizhou lead - zinc metallogenic area . the enrichment coefficient of ge and cd in main ore body reaches 6978 and 3640 respectively , which shows that dispersed elements have a special geochemical behavior in this area 会泽铅锌锗镉矿床,是川滇黔成矿三角区富分散元素铅锌矿床的典型代表,其主矿体中锗、镉的富集系数分别可达6978和3640 ,显示了分散元素在该区有着独特的地球化学行为。
Based on geological , geophysical and geochemical prospecting in the huangshan nickel - copper deposit and the xiaoerquan zinc - copper deposit , the authors have predicted nonferrous metallic resources in the western part of the east tianshan mountain on the basis of regional geological , geophysical and geochemical data obtained by the multi - statistics method and the gis spatial analysis method 摘要利用区域地物化资料,采用多元统计方法及gis空间分析技术,通过对东天山成矿带中黄山铜镍矿床、小热泉子铜锌矿床的地质、地球物理、地球化学特征的分析,对东天山西段进行了有色金属矿床找矿靶区预测。
In this paper , with the metallogenic series theory as the guide and the geochemical data as the basis , all lead - zinc ore deposits in the region were classified into two sub - series , i . e . , lf type ( with low content of iron group elements ) and hf type ( with high content of iron group elements ) , and a regional geochemical prognostic model was set up by using the logical information method 摘要以成矿系列理论为指导,将区域内的铅锌矿按地球化学特征划分为贫铁型和富铁型2个亚系列,进而用逻辑信息法建立了西秦岭铅锌矿床区域地球化学场预测模式,验证结果较为理想。
