【摘要】：火成巖及其組合的性質(zhì)不僅受巖漿系統(tǒng)本身性質(zhì)的約束,也受到成巖環(huán)境的控制。因此,火成巖分布區(qū)的地質(zhì)填圖應(yīng)當(dāng)立足于結(jié)構(gòu)可控的地質(zhì)解釋�；谶@種認(rèn)識(shí),建議侵入巖專題填圖按照巖漿系統(tǒng)的幾何尺度及其與動(dòng)力系統(tǒng)的關(guān)系劃分填圖單位。一級(jí)巖漿系統(tǒng)受控于全球動(dòng)力學(xué)系統(tǒng),具有最大的幾何尺度;二級(jí)巖漿系統(tǒng)與區(qū)域地質(zhì)歷史有關(guān),是全球動(dòng)力系統(tǒng)與巖石圈系統(tǒng)相互作用的產(chǎn)物;三級(jí)巖漿系統(tǒng)受控于局部動(dòng)力系統(tǒng),與全球動(dòng)力系統(tǒng)沒(méi)有直接聯(lián)系;四級(jí)巖漿系統(tǒng)受控于巖漿動(dòng)力系統(tǒng)與圍巖動(dòng)力系統(tǒng)的相互作用,通常與巖漿產(chǎn)量和通道條件緊密聯(lián)系在一起;五級(jí)巖漿系統(tǒng)受控于具體的巖漿過(guò)程,通常是侵入巖區(qū)的最小填圖單位。但是,巖漿系統(tǒng)具有可無(wú)限細(xì)分的特點(diǎn),填圖過(guò)程中可根據(jù)具體情況進(jìn)一步劃分更次級(jí)的巖漿系統(tǒng)。對(duì)于幾何尺度小于地質(zhì)圖表述能力的巖漿系統(tǒng),建議制作局部放大的專題地質(zhì)圖件,以展示特定巖漿系統(tǒng)的地質(zhì)特征。
[Abstract]:The properties of igneous rocks and their assemblages are not only restricted by the magmatic system itself, but also controlled by diagenetic environments. Therefore, the geological mapping of igneous rock distribution area should be based on the structure controlled geological interpretation. Based on this understanding, it is suggested that the topographic mapping of intrusive rocks should be divided into mapping units according to the geometric scale of magmatic system and its relationship with dynamic system. The primary magmatic system is controlled by the global dynamic system and has the largest geometric scale, and the secondary magmatic system is related to the regional geological history and is the product of the interaction between the global dynamic system and the lithosphere system. The tertiary magmatic system is controlled by the local dynamic system and has no direct connection with the global dynamic system; the fourth grade magmatic system is controlled by the interaction between the magmatic dynamic system and the surrounding rock dynamic system, The fifth grade magma system is controlled by the specific magma process and is usually the smallest mapping unit in the intrusive rock area. However, the magmatic system is infinitely subdivided, and the more secondary magmatic system can be further divided according to the specific conditions in the mapping process. For magmatic systems whose geometric scale is smaller than that of geological maps, it is suggested to make locally enlarged thematic geological maps to show the geological characteristics of specific magmatic systems.
