PAGS-SEGSC Lecture Notes of Dr. Graciano Yumul Jr.
Dr. Yumul gave a lecture on "Economic Geology: An exploration perspective" as part of the tutorial series organized by the Philippine Association of Geology Students - Society of Economic Geology Student Chapter last June 12, 2021. A copy of his presentation may be downloaded in this link.
Evolution of arc systems: New findings and perspectives
Our special issue on the evolution of arc systems is now available in the Journal of Asian Earth Sciences (JAES): X. This journal is the open access journal of JAES so papers are accessible and downloadable for free. The special issue highlights our ongoing research collaboration on geosciences being implemented by the Philippines Department of Science and Technology, and the Taiwan Ministry of Science and Technology.
