新疆东昆仑三岔顶地区水系沉积物地球化学特征及找矿方向研究

通过开展三岔顶一带1:5万水系沉积物测量,分析了研究Au,Ag,Cu,Pb,Zn,W,Sn,Mo,As,Bi,Sb,Cr,Ni,Co,Hg,Cd共16种元素地球化学参数特征及其相关性,认为该区元素的富集与地层、构造、岩浆岩明显相关;Hg,Cr,Ni,W,As,Au,Pb,Zn等元素变异系数较大,易于形成异常;Ag,As,Au,Co,Cr,Cu,Hg,Ni,Sb,Zn等10种元素不同程度富集,成矿可能性大。通过因子分析,提取了6种具有代表性的因子组合类型,讨论了各元素空间分布特征。全区共圈定31处地球化学综合异常,在综合异常查证的基础上,结合区域成矿地质条件、矿产地质特征,圈定出寒凝泉铬钴镍铜、黄沙河东铜银钼铅多金属、月牙湾铜银铅锌多金属3处找矿远景区,为该地区进一步开展找矿工作提供了基础地球化学依据。

平阴县浅层地下水地球化学环境质量评价

平阴县浅层地下水调查采样密度为1点/16km2,分析测试27项指标的含量变化规律后,认为调查区浅层地下水中除K,Mn,NO-2等指标含量变化较大,局部富集外,其他指标含量变化小,在浅层地下水中分布较均匀.选择As,Ba,Be,Cd,Co,Cu,Fe,Hg,Mn,Mo,Ni,Pb,Se,Zn,F-,Cl-,Cr6+,NO-2,COD,pH等20项指标,按<地下水质量标准>对浅层地下水环境质量进行的单因子和综合评价,结果显示较好级以上者达88.4%,而较差级仅占11.6%,无极差级分布,调查区内浅层地下水环境质量状况良好.

遍地是神灵

正一个岩洞,一块石头,一棵古老的榕树,都可以成为焚香祭拜的场所。祭品不在乎多少,需要表达的只是一份心意与虔诚。汉人们相信,神灵遍布和依附于世间万物,人的生老病死、兴衰祸福,都由冥冥之中的神灵主宰。风调雨顺,五谷丰登,是由上天所赐;洪涝旱灾,山崩地陷,亦因神灵恼怒所致。因而,人们敬畏天地,敬畏所有的神灵。自然界的日月星辰,风雨雷电,山川湖泊,花草树木等等,都会受到祭拜;华夏始祖,氏族先人,英雄人物,民族功臣等等,也会被当作神灵     

Geochemistry of some elements in sediments of the East China Sea

The East China Sea is noted for its vast continental shelf.The marine geology ofthe East China Sea has been extensively studied for many years.New data concerningthe seabed sediments have been published by many investigators,whereas geochemical studieson the sediments have been comparatively few.200 samples of different types of sedi-ments were analyzed to find out the geochemical characteristics of some major and traceelements in the sediments of the East China Sea.The elements determined are Fe,Mn,Ti,P,Si,Cu,Co,Ni,Zn,B,Zr,U,Th,Ra and REE(total rare earth elements).Fe,Mn,Ti,P,B,Zr,U,Th and REE were determined by ordinary colorimetry,Cu,Co,Ni

招平断裂带中段构造原生晕地球化学特征及找矿模型

招平断裂带是胶西北地区重要的金矿成矿带,该带上已发现多个特大型、大型、中型金矿床,金矿床的成矿具有多期、多阶段叠加的特点。该文对招平断裂带中段深部构造地球化学特征进行了研究,成矿元素异常组合为Au,Ag,Cu,Pb,Zn,As,Sb,Bi,B,Hg,Mo,As,Sb,Hg为头晕指示元素;W,Bi,Mo,Sn为尾晕指示元素;近矿指示元素为Au,Ag,Cu,Pb,Zn。据此建立了构造地球化学找矿模型,确定了构造地球化学找矿预测标志,为深部找矿提供了地球化学依据。     

焦家金矿深部原生晕地球化学特征

焦家金矿是胶西北地区典型的金矿床,该区成矿具有多期、多阶段叠加共同作用的特点。通过对典型剖面上钻孔不同部位岩性样品的微量元素测试分析,运用数学地质分析方法,对焦家金矿床深部地球化学特征进行了研究,得出深部成矿微量元素特征组合为Au,Ag,Cu,Pb,Zn,As,Sb,Bi,Hg,W,Mo,Sn;原生晕轴向分带序列为:Hg,As,Sb(矿头晕)→Au,Ag,Cu,Pb,Zn,Bi,Sn(矿中晕)→W,Mo(矿尾晕)。由此建立了地球化学原生晕异常模型,并总结了地球化学找矿标志,为深部找矿提供依据。
