This technical record presents primary geological data from the mapping project of the Putussibau, Pegunungan Kapuas, and Nanga Obat quadrangles in West Kalimantan. The document provides detailed observations on lithology, structural geology, and regional stratigraphy based on systematic field surveys. Produced through an international cooperation between Indonesia and Australia, this record se…
Tectonostratigraphic Terranes of the Circum-Pacific Region is a seminal volume that provides a systematic framework for the study of crustal blocks or "terranes" across the Pacific basin. Edited by David G. Howell, the book defines these terranes as fault-bounded geologic entities with unique stratigraphic and geologic histories that distinguish them from adjacent regions. The text integrates p…
Carbonate Depositional Environments is a comprehensive reference work that provides a detailed examination of the settings in which carbonate rocks are formed. The book is structured into several sections, each focusing on a specific depositional environment, ranging from non-marine settings like lakes and caliches to deep-marine environments such as slopes and basins. Each chapter typically in…
