Sedimentology And Ore Genesis

Sedimentology and Ore Genesis

The papers in this volume are dedicated to Professor Dr. Dr. h.c. G. Christian Amstutz by his colleagues, friends, and students on the occasion of his 60th anniversary. The authors of this book - the theme was restricted to syngenesis and epigenesis in the formation of mineral deposits - wish to honour with their articles a scientist who has contributed to, and substantially promoted the understanding of the genesis of mineral deposits in the last decades. The majority of the articles deal with strata-bound depos its, thus reflecting one of his main scientific interests. In the tradition of his professors, Paul Niggli and Paul Ramdohr, G.C. Amstutz has maintained an open and active interest in many fields of earth science. His numerous papers have triggered a remarkable number of new ideas and investigations in a variety of fields, and the "happy marriage" of economic geology with sedimentology is cer tainly one of his main successes, starting with the first Symposium on Sedimentology and Ore Genesis at the Sixth International Sedimentological Congress at Delft in 1963.

In 1963 the first Symposium on "Ores in Sediments" took place as part of an Inter national Sedimentological Congress. At the end of that first Symposium. the group then assembled adopted a resolution printed in the book which resulted from it (AM STUTZ. 1964, p. 7). and points (3). (4) and (5) read as follows: (3) The group considers the integration of sedimentology in any study of ore deposits in sediments essential to a correct interpretation. A study of the role of sedi mentary processes, including diagenesis, is an important field in pure as well as in applied research on the genesis of mineral deposits. (4) In particular. the group also considers the knowledge of sedimentary rocks and processes (in regard to both. the fabric and the geochemical detail) a prerequi site for the understanding of subsequent metamorphic processes and their pos sible role in the deformation and reconstitution of mineral deposits and host rocks. (5) The group suggests that similar symposia could with advantage be held at future Congresses of the International Association of Sedimentologists. The Editors wish to thank the International Association of Sedimentology for includ ing another Symposium on ore minerals in its Congress program.
