Phase analysis of thallium is not only the research objective of thallium migration and ecosystem effect of thallium in nature environment , but also the guide to find hidden large scale deposit such as ti , au , hg , as and sb ore 摘要鉈的相態(tài)分析既是研究自然環(huán)境中鉈的遷移和生態(tài)效應(yīng)的指標(biāo),也是指示尋找大型隱伏礦床如鉈、金、汞、砷、銻等礦的手段。
Besides fankou , dabaoshan and yingde are known large non - ferrous metal and pyrite bed , other medium and small scale deposits and mineralized spots scatter everywhere . these depositsmostlty exist in the middle - late devonian strata , others exist in carboniferrous 除著名的凡口、大寶山以及英德等幾個(gè)大型有色金屬及硫鐵礦礦床外,其他中、小型礦床及礦點(diǎn)更是星羅棋布。
In order to solve corrosion and heave scale deposit of water injection pipeline in zhongyuan pucheng oilfield 2 . 5inch tbs2510ij glass fiber reinforced plastic pipe was used as water injection peip in two single well respectively in decemher of 1997 and january of 1998 . its application results in good effect and is worth being populated 總結(jié)在黃土高原儲(chǔ)罐基礎(chǔ)施工中處理瀝青砂墊層裂紋和凹凸度超標(biāo)的實(shí)踐經(jīng)驗(yàn),分析了缺陷成因,提出了處理和預(yù)防措施,實(shí)施效果良好。
The efficiency and reliability of minerogenetic prediction can be improved by combining rs with gis . we processed rs images , extracted the geological information related to mineralizing , such as geology , structures , stratam , rocks , etc , synthetically analysed remote sensing , the geological data and geo - chemistry , under the guidance of the theory and mathematic model , set up gis mineralize model . on this condition , to develop this method and its theory , and to establish a system of perfect prediction , it is not only useful in studied degree area but also favorable for looking for new type and some form large - scale deposits in old studied area , and it has a great theoretical meaning 遙感與gis相結(jié)合用于成礦預(yù)測(cè)中可大大提高預(yù)測(cè)工作的效率和可靠性。通過對(duì)研究區(qū)的遙感圖像處理和地質(zhì)、構(gòu)造、地層、巖石、礦化蝕變等有關(guān)信息的特征提取、遙感、地質(zhì)數(shù)據(jù)和物化探數(shù)據(jù)的綜合與復(fù)合分析,在一定成礦理論和數(shù)學(xué)模型指導(dǎo)下,建立gis綜合找礦模型。在此基礎(chǔ)上,發(fā)展這一方法及理論并建立完善的預(yù)測(cè)體系,不僅對(duì)研究程度較低的新區(qū)礦床預(yù)測(cè)有用,而且對(duì)研究程度較高的老區(qū)尋找新類型和點(diǎn)狀大型、超大型礦床都具有重要理論意義和實(shí)際意義。
Based on the analysis of the data on global metallogeny in the framework of geodynamics and study of the processes of continental evolution and metalloeny of of sanjiang , qinling and xingan - mongolia orogenic belts , we have reconsidered the geodynamic evlution and metallogeny during indosinian to early - yanshan movement in china , and established large - scale metallogenic model on intracontinental evolution we in orogenic belts . the main results are summarized as follow . ( 1 ) systematically gathering the data about large - scale and superlarge - scale deposits in the world and drawing up the map of global tectonics and metallogeny ; finding out the segmentation of circle - pacific ocean metallogenic belt and informing that the giant deposit clusters are the prominent feature of global metallogeny 本文在總結(jié)全球大規(guī)模成礦的地球動(dòng)力學(xué)背景資料基礎(chǔ)上,通過深入解剖和系統(tǒng)對(duì)比我國(guó)三江造山帶南段、東秦嶺造山帶和興蒙造山帶中南部等典型造山帶關(guān)鍵地區(qū)以陸內(nèi)演化過程為核心的地球動(dòng)力學(xué)演化歷史及其成礦特征,重新認(rèn)識(shí)了我國(guó)大陸印支?早燕山期的動(dòng)力學(xué)演化過程及其成礦效應(yīng),建立了關(guān)于造山帶陸內(nèi)演化階段主要過程中的大規(guī)模成礦模式。
