早期成岩作用研究进展及发展方向

早期成岩作用作为一个重要的研究领域受到广泛关注。概括总结了早期成岩作用的主要特点、地质响应和研究思路,介绍了在元素的迁移转化、硫酸盐还原反应、数学模型及微生物成岩等理论领域和多金属结核及早期成岩成矿、环境沉积学、土壤性质评价与改良等应用领域的主要研究进展。早期成岩作用研究具有广阔的发展前景,未来可能在以下3方面快速取得突破:研究区域将进一步扩大,湖泊、三角洲及土壤中的相应研究将得以加强;多层的稳态或非稳态的一维、二维或三维的早期成岩数学模型将得以建立;其研究方法和理论成果将被广泛应用于环境沉积学及环境监测和治理等领域中。

Research evolution and development direction in the early diagenesis

Early diagenesis, an important study subject, has been given extensive attention. The main characters, geological response and study methods of the early diagenesis were summarized. The theoretical progresses on movement and transform of elements, the process of sulfate reduction, mathematical models, microorganism action during early diagenesis, and the application to multi-metal nodules and early diagenesis and mineralization, environmental sedimentology and soil estimation were stated systematically. Early diagenesis has broad and bright prospects not only in theory but also in application, and three future trends are predicted. First, the area of early diagenesis study will be enlarged widely to lake, delta, soil. Then, the stable or nonstable one-dimensional, two-dimensional or three-dimensional multi-layer early diagenesis models will be established, and the methods and theoretical achievements of early diagenesis will be widely applied in environmental sedimentology to supervise and treat environment pollution.
