【摘要】：為了更好地發(fā)揮遙感技術(shù)在我國西部艱險復(fù)雜地區(qū)地質(zhì)找礦工作中的作用,利用World View2,Quick Bird,IKONOS,ASTER和ETM+等多元遙感數(shù)據(jù),采取去相關(guān)、比值計算、主成分分析和圖像融合等圖像處理方法,在西昆侖成礦帶黑恰達(dá)坂一帶開展了1∶50 000遙感地質(zhì)解譯和遙感異常提取研究,對黑恰達(dá)坂附近的菱鐵赤鐵礦礦化帶分布情況進(jìn)行了調(diào)查,并通過野外驗證快速圈定了溫泉溝群的含鐵層位。該礦化帶賦存在下志留統(tǒng)溫泉溝群,延伸長約120 km,其西北部被巖體侵蝕,東南部被喀拉塔格斷裂截切,具有層位穩(wěn)定、沿走向傾向連續(xù)性好、規(guī)模大的特征,是開展礦產(chǎn)資源調(diào)查工作的有利地區(qū)。調(diào)查結(jié)果表明,遙感技術(shù)已經(jīng)成為地質(zhì)礦產(chǎn)調(diào)查工作不可或缺的手段之一,必將在地質(zhì)找礦工作中發(fā)揮重要作用,加速區(qū)域找礦突破進(jìn)程。
[Abstract]:In order to better play the role of remote sensing technology in geological prospecting in the difficult and complex areas of western China, image processing methods, such as de-correlation, ratio calculation, principal component analysis and image fusion, are adopted by using multivariate remote sensing data, such as World View2 Quick Birdfly, IKONOSERASTER and ETM, etc.The 1:50 remote sensing geological interpretation and extraction of remote sensing anomalies have been carried out in Heichadaban area of the West Kunlun metallogenic belt. The distribution of the magmatorite mineralization zone near Heichadaban has been investigated.The iron-bearing horizon of the hot spring gully group was quickly delineated by field verification.The mineralization zone is located in the Lower Silurian hot spring gully group with an extension of about 120 km. The northwestern part of the zone is eroded by rock mass, and the southeastern part is cut off by Karatagh fault, which has the characteristics of stable horizon, good continuity along the strike trend and large scale.Is carries out the mineral resources investigation work the advantageous area.The results show that remote sensing technology has become one of the indispensable means of geological and mineral exploration, and will play an important role in geological prospecting and accelerate the process of regional mineral exploration breakthrough.
