摘　　要：岩浆岩是地球上最重要的地质体之一,数字岩浆岩是数字地球的重要内容。本文综述了这方面的研究进展,主要包括岩浆岩数据库创建及其应用研究取得的重要进展。研究团队创建了国内首个岩浆岩数据库及研究平台,核心数据和平台功能在某些方面已优于国际已有数据库。基于这些数据,研究团队编制并发布了一系列数字化全球岩浆岩、亚洲岩浆岩和深时岩浆岩图,取得了以下重要研究进展:1)创建了亚洲花岗岩时空演化格架,提出亚洲大陆平直、弯曲旋转、剪刀状3种方式和5个阶段的聚合模式;2)通过对比全球8个典型造山带同位素填图,确定了从典型增生到典型碰撞不同类型造山带的深部物质架构特征,鉴别出显生宙巨量地壳生长,丰富了地壳生长理论;3)定量刻画了深部物质架构及其成矿制约,构建了深部物质探测方法体系框架,提出造山带分类和物质造山带新概念,为深化认识造山带奠定了理论基础。As magmatic rocks represent one of most significant geological records on Earth,digital magmatic rocks are an important component of the digital Earth.This study reviews the progress of research in this field,including the construction of a global magmatic rock database and its applications.The development of the first domestic magmatic rock database and research platform has achieved core data and platform functions that surpass some aspects of existing international databases.Based on these data,a series of digital maps of global,Asian,and deep-time magmatic rocks were compiled and published.Notably,the following significant enhancements have been made:1)A spatiotemporal evolution framework for Asian granites has been established,proposing three modes(straight,curved rotation,and scissor-like)and five stages of the Asian continent assembly.2)By comparing isotopic mapping of eight typical orogenic belts worldwide,the deep material architecture characteristics of different types of orogenic belts have been identified,revealing significant crustal growth during the Phanerozoic and enriching the theory of crustal growth.3)The deep material architecture and its constraints on mineralization have been quantitatively characterized,a framework for a deep material exploration method system has been developed,and new concepts of orogenic belt classification and material orogenic belts have been proposed.These findings contribute to a deeper understanding of orogenic belts.
