Abstract
En este trabajo se realiza una puesta al día sobre los hitos más relevantes y las aportaciones de la Petrología Sedimentaria. Para ello se define cual es su objeto de estudio y su interés científico y aplicado. La parte más
importante del trabajo se centra en el desarrollo histórico de la Petrología Sedimentaria, desde las épocas iniciales
de Sorby, hasta la actualidad. Como hitos relevantes señalaremos: 1) los trabajos iniciales más descriptivos,
2) los estudios experimentales, 3) el establecimiento de las clasificaciones de las rocas sedimentarias, 4) los estudios de caracterización de facies y ambientes sedimentarios, 5) los avances en el conocimiento de los procesos diagenéticos y su importancia en la prospección de hidrocarburos, 6) el desarrollo de la Geoquímica Sedimentaria. Se discuten las relaciones y coincidencias con la Sedimentología, para terminar resaltando los avances realizados en los últimos 30 años, en los que el estudio de las rocas sedimentarias se incluye necesariamente en los modelos que ofrecen una visión más global de nuestro planeta y formando parte del campo
más amplio de la Geología Sedimentaria. La última parte del trabajo se dedica a la situación de la Petrología Sedimentaria en España.
We describe here the most important milestones and contributions to Sedimentary Petrology compared to other geological disciplines. We define the main aim of our study and the scientific and economic interests involved in Sedimentary Petrology. The body of the paper focuses upon the historical development of this discipline from Henry Sorby´s initial work until the present day. The major milestones in its history include: 1) initial descriptive works; 2) experimental studies; 3) the establishment of the different classifications of sedimentary rocks; 4) studies into facies and sedimentary environments; 5) advances in the study of diagenetic processes and their role in hydrocarbon prospection; and 6) the development of Sedimentary Geochemistry. Relationships and coincidences with Sedimentology are discussed. We go on to look at the advances that have taken place over the last 30 years, in which the study of sedimentary rocks is necessarily included in the wider field of Sedimentary Geology as a logical result of the proposal of global models of a changing Earth in which Sedimentary Geology plays a significant part. Finally we mention the notable contributions of Spanish sedimentary petrologists to this whole field of science
