Abstract A reversed pleochroism phlogopite is discovered for the first time in Houxianyu borate deposit, Liaoning province, in the course of mineralogical researches on the endogenetic borate deposits across the Liaoning- Jilin region. Unlike normally pleochronic phlogopite,the anomalously optieal mineral tends to increase in amount progresively towards the bodies until almost entirely taking the place of the former inside them. Support for the increase is drawn through electric probe and Mossbaure spectra examinations...

Abstract A reversed pleochroism phlogopite is discovered for the first time in Houxianyu borate deposit, Liaoning province, in the course of mineralogical researches on the endogenetic borate deposits across the Liaoning- Jilin region. Unlike normally pleochronic phlogopite,the anomalously optieal mineral tends to increase in amount progresively towards the bodies until almost entirely taking the place of the former inside them. Support for the increase is drawn through electric probe and Mossbaure spectra examinations revealing that,when vacuities take place in the Al3+ sites of the crystal tetrahedrons of normal phlogopite, Fe3+ will displace the Al3+ into the tetrahedrons. Under the Al - poor oxidative conditions, once the Fe3+ displacements exceed 22% the normally pleochronic phlogopite would convert into reversely pleochronic ones. As genesis- definting mineral,this sort of phlogopite As genetic ty pomorphic mineral,may also be a guide mineral to prospecting for endogenetic borate deposits.

在对辽吉内生硼矿床的矿物学研究中,笔者于营口后仙峪硼矿床首次发现了反吸收的金云母。相对于正常金云母,从围岩到矿体逐渐增多,矿体中几乎均为反吸收性的金云母。对其进行的电子探针以及穆斯堡尔谱的研究表明,同正吸收的金云母相比,反吸收性金云母的Si-Al四面体位置上Al3+亏损,Fe3+替代Al3+占据四面体位置;当金云母四面体中Fe3+的量是总铁量的22%以上,即在一种相对贫Al氧化的条件下就形成反吸收性的金云母。它具有明显的成因标型特征,对找寻硼矿具有重要的指示意义

Abstract In the paper,minerals of ludwigite-vonsenite series are studied for endogenetic borate deceits in Liaoning -Jilin Region.These minerals include rich-Mg vonsenite,rich-torn ludwigite and rich-Mg ludwigite.Their mineralogy characters depend on ratio between FeO and(FeO + MgO).When FeO/(FeO+ MgO) increase, reflecting colour,reflection pleo-chroism and polarization colour are apparent, the viberation frequences of υ2 and υ4 are decreased in infrared spectroscopy and the unit cell parameters(a,C0) are increased.From...

By analyses and comparison, An, Sb, As, Mo, Hg and Bi are determined as practical indicator elements for gold-antimony prospecting in this area. Metallogenic prognosis for the...

In this paper geochemical features of microelements of Fuzhuxi gold-antimony deposit are studied,and correlation analyses have been done on microelements in rocks and ores of the deposit. So the ten indicator elements of gold and antimony in Fuzhuxi area are selected and determined, which include An, Sb, As, Mo, W, Hg, Pb, Ag, T1 and Bi. By analyses and comparison, An, Sb, As, Mo, Hg and Bi are determined as practical indicator elements for gold-antimony prospecting in this area. Metallogenic prognosis for the deeper part of the deposit are conducted by using elements' axial zonality and their ratio index,which are demonstrated by exploration engineering, ore bodies of gold grade up to 44 × 10-6 being found.Therefore,the tense situation about An and/or Sb ore resources was eased up in the mine,and economic benefit became remarkable. Moreover,three prospective sectors are selected in the area (the part near the deposit and its periphery) by geochemical exploration,which are Zhuyeshan sector south of deposit,Yangjiachong and Tianzhuangwan sectors in the periphery.

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。
