Looking back on the past and looking forward to the future, the development of sedimentary petrology is closely related to human survival and the development of energy industry.
C. Leyer was the founder of modern geological science. In 1830, Leyer published the epoch-making Principles of Geology, established a realistic method of geological research, and became a guide for all aspects of geological research. "Modernity is the key to the past" is to clarify the realist method. Nowadays, we often use the term "discussing the present and the ancient" or "comparative geology" to express the realist method. After the publication of Principles of Geology, Leyle's realistic geological concept became the dominant idea in the study of geology. In 1894, J. Walther published his monograph Introduction to Geology as a Historical Science. In this monograph, Walther's law of facies sequence, which is widely used today, makes geology and sedimentology a comparatively systematic geological science. Later, Swiss geologists put forward the concept of facies when they studied glacial deposits in the Alps. From 1837 to 1842, C. Darwin studied coral reefs while traveling around the world with the Challenge.
Sedimentary petrology, as an independent discipline, appeared in the second half of the 19th century. Sorby (1850), a British geologist, was the founder of sedimentary petrology. He was the first scientist to study sedimentary rocks under a microscope. Since then, the research field of sedimentary petrology has gone from macro to micro, which is a breakthrough development.
From 1894 to 1931, sedimentology entered the stage of specialization. Sound sounding technology was used to detect water depth and X-ray diffraction technology was used to study the composition of fine sediments. In 1913, Glip published his book "Stratigraphic Principle h 1914, which reflects the realism principle. Gilbert used flume experiments to study the mechanism of sedimentation. In 1926, C. K. Wentworth proposed that the grain size limit of debris particles should be divided into two powers according to the law of hydrodynamics, and the upper limit of grain size should be 2 mm diameter. In 1913, the American Society of Economic Paleontologists and Mineralogists published Volume 1 of the Journal of Sedimentary Petrology, which became a symbol of the specialization of sedimentology. '
By the first half of the 20th century, sedimentary petrology had developed in an all-round way, especially in the aspects of sedimentary rocks, diagenesis, quantitative study of sedimentology, and the relationship between sedimentation and tectonism. During this period, some representative monographs and textbooks on sedimentary petrology were published in European and American countries, such as Hatch and Lastel's Sedimentary Petrology, Milner's Introduction to Sedimentary Petrology, Milner's (1929, 1940), Twenhofol, 1, 1938. 925, 1932, Twenhofol (1939, 1950), Pettijohn (1949), Krumbein and Sloss (1950), Stratigraphy and Sedimentation, etc.
In the 1940s and 1950s, the sedimentary petrology of the former Soviet Union had a great potential to follow, such as IlycTO BajioB's Sedimentary Petrology, NiBeuoB's Sedimentary Petrology, PyxHH's Principles of Sedimentary Petrology, CTpaxB's Research Method of Sedimentary Rocks, Pyxrni's Sedimentary Petrology. The Handbook of Petrology and Principles of Sedimentary Petrology edited by CTpaxB have made new progress in sedimentary petrology. These books and textbooks are widely used in China and have a great impact.
From 1960s to 1970s, the development of sedimentary petrology was first manifested in the presentation of turbidity theory (Kuenen and Mighiorini, 1956) and its perfection (Bouma, 1%2). Later, turbidity theory developed into sediment gravity flow theory.
(Walker, 1973; Middleton and Hampton, 1976), the emergence of this theory promoted the development of deep-water sedimentary research; followed by the proposal and establishment of a genetic classification of carbonate rock structure (Folk, 1959, 1962; Dunham, 1962), carbonate sedimentary facies model (Irwin, 1965; Laporte, 1967; Young et al., 1972; Armstrong, 1974; Wilson, I975) and dolomite genesis. The development of Carbonate Diagenesis (Batnarst, 1971). The representative works of this period include "Sedimentary Rocks" (Third Edition) (Pettijohn, 1975), "Genesis of Sedimentary Rocks" (Blattetal., 1972, 1980), "Introduction to Selly, 1976", "Sedimentary Environment and Facies" (H. Reading, 1978), and "Principles of Sedimentology" (Friedman and Sanders, 1978). It can be said that the 1960s and 1970s were great in sedimentological petrology and sedimentology. During the period of development, it has become an important branch of geology.
From the 1980s to the early 21st century, sedimentary petrology developed to the stage of sedimentology. Sedimentology is a discipline that systematically studies sedimentation, sedimentary process and formation mechanism of sedimentary rocks. The rise and development of global deep-sea drilling and plate tectonics has greatly promoted the development of sedimentology. During this period, people strengthened the study of deep-water sediments, such as isobatic currents, storm currents and deep-water tides, and strengthened the application of research results of sedimentary reservoirs in exploration and development of sedimentary mineral resources, such as lithologic reservoirs. The most important feature is that a large number of interdisciplinary disciplines, such as practical sedimentology, sequence stratigraphy and seismic sedimentology, have emerged.
