摘要
内蒙古羊蹄子山沉积变质型钛矿床是一个新的钛矿床类型。通过对地质、地球物理前提条件的研究和找矿方法试验,认为高精度磁法是找沉积变质型钛矿床的基本方法,重力为有效的找矿方法。在矿区北带磨石山以金红石为主的富钛矿体上有600μGal的重力异常,无磁异常;南带的羊蹄子山钛铁矿体上重力异常为500μGal,有60nT的弱磁异常。
The Yangtizishan diagenetic-metamorphic titanium deposit in Inner Mongolia is of a new type. Based on the study of geological and geophysical prerequisite and the test of ore-prospecting methods, the authors hold that the high-precision magnetic method is the basic method in search for the diagenetic-metamorphic titanium deposit, and gravity survey is an effective ore-prospecting method. Over the Moshishan rutile - dominant titanium-rich ore body in the northern belt of the ore district there is a gravity anomaly of 600 μGal with no magnetic anomaly, whereas over the Yangtizishan titanium ore body in the southern belt there occurs a gravity anomaly of 500 μGal together with a weak magnetic anomaly of 60 nT.
