江西宜春地区锂矿床地质特征及找矿远景分析

江西宜春地区锂等稀有金属矿床分布在九岭隆起带和武功山隆起带内,主要有风化壳型、钠化花岗岩型、细晶岩脉型共三种矿床类型,内生锂矿床与钠长石化、锂云母化白云母花岗岩密切相关。在概述宜春地区锂矿床成矿地质、地球化学异常特征的基础上,对锂矿床成因进行了探讨,总结了找矿标志,并划分出雅山、甘坊、蒙山找矿远景区。雅山南偏西震旦系千枚岩之下存在隐伏岩体,对寻找隐伏锂矿床具良好的指示作用;甘坊地区Li异常面积大,强度高,成矿地质条件优越,预测有很大的找矿潜力;蒙山地区具备锂的成矿地质条件,寻找锂矿资源的远景良好。     

贵州遵义—水城地区二叠纪锰矿成矿区带划分及找矿潜力分析

贵州遵义-水城地区二叠纪锰矿已先后发现锰矿床(点) 29个,累计提交锰矿资源储量达1. 76亿吨,所有锰矿床均位于黔北裂谷盆地分布范围内,据其特征可分为"遵义式"锰矿和"水城式"锰矿,典型矿床分别为铜锣井-深溪锰矿床和徐家寨锰矿床。结合锰矿成矿地质背景,本文将贵州遵义-水城地区二叠纪锰矿成矿带划分为遵义-黔西、水城-宣威2个锰矿成矿亚带、5个矿带和18个锰矿预测区。通过总结提取贵州二叠纪锰矿"古天然气渗漏沉积型锰矿床预测要素",根据预测要素、成矿规律开展找矿潜力分析,预测遵义-水城二叠纪锰矿成矿带资源潜力2. 45亿吨,找矿潜力巨大。

中国铝土矿资源潜力预测评价

铝土矿是铝的主要来源,我国铝土矿的产量和储量均居世界前列。为摸清我国铝土矿资源家底,制定合理的经济产业政策,需要对铝土矿资源潜力进行准确预测。我国铝土矿可分为沉积型、堆积型和红土型,以沉积型为主,占总资源储量的80%以上。沉积型主要成矿时代为石炭纪和二叠纪,而堆积型和红土型为第四纪。铝土矿的成矿与碳酸盐岩和基性岩基底有关,受岩相古地理条件、古气候条件、古地貌等条件控制。在地质研究基础上,划分了18个铝土矿成矿区带,其中山西断隆区、华北陆块南缘、桂西南、桂中南、黔中等为最重要的成矿区带。在典型矿床研究的基础上,分析了三种类型铝土矿的预测要素,并建立了预测模型.采用矿床模型综合地质信息预测方法,利用计算机信息技术(特别是GIS技术),挖掘成矿信息,编制预测要素图,并采用成矿地质体体积法估算了2 000m深度以浅预测资源量。预测结果表明,我国铝土矿1 000m深度以浅有较大找矿潜力,目前资源查明率仅为35.6%,除河南、广西、山西、贵州等资源大省外,云南、重庆、山东、河北、陕西也具较大的找矿远景。预测结果为铝土矿勘查工作部署提供了科学依据。

综合找矿模型在甲基卡隐伏区稀有锂金属找矿中的 应用

锂金属是重要的战略新兴关键矿产之一。寻找超大型稀有锂金属隐伏矿是中国矿床学界的一大难题。甲基卡广为第四系覆盖,以往的找矿和勘查工作主要局限在南部"就脉找矿"。笔者通过对超大型X03锂矿床的找矿实践,建立了"岩浆-变形-变质-成矿"四位一体控矿要素和成矿模式,归纳总结了地质-地球物理-地球化学异常的内在关联,从远景区分析、找矿靶区圈定、矿床(矿)预测定位的层次与流程,建立的第四系掩盖区隐伏稀有锂金属的综合找矿模型,在指导稀有金属找矿中取得了快速突破,是一个典型的成功实例。建议继续加强该矿田花岗岩基的深部延伸及岩石组合特征、伟晶岩(矿)脉的形成富集规律等研究,注重隐伏花岗岩株(枝)与伟晶岩(矿)脉的找矿相连部位的找矿,开展深部锂等稀有金属的资源潜力预测。

Définition d'une limite multicritère ; stratigraphie du passage Campanien–Maastrichtien du site géologique de Tercis (Landes,SW France)Definition of a multi-criteria boundary; stratigraphy of the Campanian–Maastrichtian interval of the geological site at Tercis (Landes,SW France)

Lithostratigraphy, physicochemical stratigraphy, biostratigraphy, and geochronology of the 77–70 Ma old series bracketing the Campanian–Maastrichtian boundary have been investigated by 70 experts. For the first time, direct relationships between macro- and microfossils have been established, as well as direct and indirect relationships between chemo-physical and biostratigraphical tools. A combination of criteria for selecting the boundary level, duration estimates, uncertainties on durations and on the location of biohorizons have been considered; new chronostratigraphic units are proposed. The geological site at Tercis is accepted by the Commission on Stratigraphy as the international reference for the stratigraphy of the studied interval. To cite this article: G.S. Odin, C. R.

Late Wuchiapingian (Late Dzhulfian,early Late Permian) limestone olistolites within the Tertiary flysch of Glypia Unit (Mount Parnon,central–eastern Peloponnesus,Greece)

Some olistolites reworked in a Tertiary flysch of Mount Parnon (Peloponnesus, Greece) exhibit a Late Permian assemblage, dominated by Paradunbarula (Shindella) shindensis, Hemigordiopsis cf. luquensis and Colaniella aff. minima. This association corresponds to the Late Wuchiapingian (=Late Dzhulfian), a substage whose algae and foraminifera are generally little known. Contemporaneous limestones crop out in the middle part of the Episkopi Formation in Hydra, but they are rather commonly reworked in Mesozoic and Cainozoic sequences. The palaeobiogeographical affinities shared by the foraminiferal markers of Greece, southeastern Pamir, and southern China, are very strong (up to the specific level), and are congruent with the Pangea B reconstructions.
