【摘要】：Tilt-Depth以及其相關(guān)改進(jìn)方法最初是基于磁異�；竟酵茖�(dǎo),一直應(yīng)用于磁法勘探領(lǐng)域。自2012年以來,不斷有學(xué)者探討重力場Tilt-Depth方法,但對重力場與磁場Tilt-Depth方法之間的關(guān)系研究較少,存在一些不同認(rèn)識。梳理了重磁場之間Tilt-Depth方法的聯(lián)系與區(qū)別,得出了Tilt-Depth方法在重力場中相比磁場高一階導(dǎo)數(shù)的結(jié)論。驗(yàn)證了方法的有效性,通過對海南石碌礦區(qū)重力異常處理,提取了礦體的邊界信息,突出了深部隱伏礦體產(chǎn)生的弱異常的邊界范圍,獲取了礦體的位置及埋深參數(shù),通過與已知地質(zhì)剖面、反演剖面的對比,證實(shí)了重力場Tilt-Depth結(jié)論的正確性與有效性。
[Abstract]:Tilt-Depth and its related improvement methods are initially based on the derivation of basic magnetic anomaly formula and have been applied to the field of magnetic prospecting. Since 2012, there have been many scholars on the Tilt-Depth method of gravity field, but there are few studies on the relationship between the gravity field and the magnetic field Tilt-Depth method, and there are some different understandings. The Tilt between the heavy and magnetic fields has been combed. The relationship and difference between the -Depth method and the conclusion of the first derivative of the Tilt-Depth method in the gravity field are obtained. The validity of the method is verified. The boundary information of the ore body is extracted from the gravity anomaly treatment in the Hainan Siu mining area, and the boundary range of the weak anomaly produced by the deep concealed orebody is highlighted, and the position of the ore body is obtained. By comparing with the known geological section and inversion profile, the correctness and validity of the Tilt-Depth conclusion of gravity field are confirmed.
