论褐煤煤岩学与加氢液化的关系

本文系统地研究了云南可保等地的褐煤岩石类型、显微组合、煤化程度与液化性能之间的关系,提出液化的转化率随褐煤的煤化程度的增高而降低,且与褐煤的反射率及凝胶化程度有较好的相关性,这与褐煤的原始物质中的沥青质和孔隙度等因素有关。     

烟煤接触变质带的煤岩学研究

近年来对山东省范围内受岩浆侵入的石炭二叠纪煤田（如淄博、黄河北、巨野、膝县等）接触变质带的研究，获得如下进展：（１）提出烟煤接触变质带的分带模式，即分为焦岩混、天然焦、煤焦混和高变煤４个带；根据结构把天然焦分为致密、砾状、柱状和砂（粒）状４种；又根据成分把砾状焦分为３种。（２）讨论了天然焦在显微结构、反射率、显微硬度和Ｘ线衍射等诸方面的特点。（３）有重点地讨论了高变煤的某些微观特点。（４）初步提出一个以煤岩方法为主兼顾其他手段（如地球物理测井、煤化学等）的综合划分煤和天然焦界线的方法。

苏北盆地是一个较为复杂的断陷－坳陷型含油气盆地，对其早第三纪烃源岩有机质热演化程度的评价是目前尚未解决的课题。应用显微组分光学标志和可溶有机组化学标志，研究了苏北盆地早第三纪烃源岩有机质热演化特征，从而揭示了有质热演的不均衡生民生与阶段性。     

Fluorometric analysis of inertinite

In coal petrology, fluorescence microscopy has mainly been used in the study of liptinite (exinite) macerals. Recently, its scope of application has been widened to investigate vitrinite. This paper describes the conditions under which inertinite can also be studied by fluorometry. The method makes use of relatively long-wave excitation. Although the strongest signals are received through a green exciter filter at 546 nm, blue light excitation (450–490 nm) is preferred because the fluorescence spectrum is broader, the microscopic image more polychromatic and maceral identification is easier compared with longer-wave excitation. Inertinite macerals are divided into fluorescent and non-fluorescent constituents on the basis of both visual distinction and relative intensity determinations at 650 nm measuring wavelength. It appears that fluorescent inertinite corresponds closely to reactive fractions determined by previous coking experiments.     

武功山区花岗质混合-岩浆杂岩的演化与成矿

大地构造的阶段性发展,为武功山区花岗质混合-岩浆杂岩的形成、演化及与其有关的金属成矿,创造了有利的构造前提。高度分异演化的地洼花岗岩(主要是燕山早期花岗岩)是该区主要的成矿花岗岩。     

克孜勒塔格地区古元古代黑山梁片麻状辉长岩—二长花岗岩序列的特征分析

在克孜勒塔格地区开展的1∶5万区域地质矿产调查工作,初步查明了此区古元古代变质花岗岩的岩石学、岩石化学等特征,对该期侵入岩的岩体成因及就位机制进行了探讨,并对其形成时代进行了推断。岩体侵位明显受线状构造("X"型剪裂隙)控制,说明该区域在地壳演化早期存在,岩体就位以构造扩展机制为主。其侵位时间为古元古代晚期。     

Machine learning approach for automated coal characterization using scanned electron microscopic images

Increased coal utilization has accelerated the need of understanding the basic knowledge of coal quality. Coal is highly heterogeneous in nature and because of its heterogeneity, numerous analytical techniques are needed for its characterization so as to predict its behavior and characteristics. Conventional analysis had been a basic technique long since for coal characterization performed by petrologists. Such conventional characterization of coal samples is time consuming and are limited by the high degree of subjectivity in the results. This paper come up with an automated image analysis approach towards the characterization of given different grades of coal samples. The objective of this work is to improve the characterization of coal samples by analyzing the textural and color features of coal using image processing techniques and to assist in the development of a preliminary screening of the coal samples. Automated characterization of coal is accomplished using image acquisition, features extraction, feature selection and classification over scanned electron microscopic images of coal samples. Hence, authentic and accurate subtyping of coal is obtained with the use of improved prominent features and a standard neural network classifier.     

接触变质煤中碳酸盐矿物成因探讨

山西大同和山东临沂煤田的接触变质煤中含有大量碳酸盐矿物，根据显微镜鉴定、化学分析、低温煤灰的Ｘ射线衍射分析、差热分析、碳同位素测定，碳酸盐的矿物成分主要为白云石和方解石，其成因主要与侵入煤层的火成岩及其伴随的富含ＣＯ２气体的气、液物质相关。     

桂北上元古界－下古生界变质构造层中的韧性变形带

桂北上无古界－下古生界变质构造层中发育有４类韧性变形带：丹洲群中的层状韧性变形带主要发育于中、下部，与丹洲群沿下不整合面的总体向东滑脱有关；三门街组基性－超基性岩中的韧性变形带是一种典型的透镜体型变形分解构造，是纯剪变形向单剪变形转化的产物；花岗岩体中的韧性剪切带主要发育于接触带的内侧，具有明显的左旋单剪效应；变质地层中的陡倾韧性剪切带则具有韧性向脆－韧性过渡特征。韧性变形带最早发育始于雪峰期，但其主变形期则与广西运动有关，是递进变形过程中顺序发展的结果，其变形变质相总体为低绿片岩相，花岗岩体中的部分剪切带可达高绿片岩相至低角闪岩相。
