Dear distinguished guests, esteemed colleagues, and friends,

It is our great pleasure to welcome you to the 42^nd Annual Meeting of the Society for Organic Petrology (TSOP 2026), to be held in Beijing, China, from September 3 to 10, 2026. This meeting is jointly hosted by China University of Mining and Technology (Beijing) (CUMTB) and Taiyuan University of Technology (TYUT). All scientific sessions and conference accommodations will be arranged at the beautiful Nirvana Resort Beijing, providing a comfortable setting for focused discussion and networking.

TSOP 2026 brings together researchers and professionals from around the world to exchange the latest advances in organic petrology and related disciplines. This year’s program is organized around three key themes: Critical Minerals in Coal, AI for Coal Geology, and Unconventional Hydrocarbon Resources. We hope these themes will inspire cross-disciplinary dialogue, new collaborations, and fresh perspectives on both fundamental science and energy resource-studies.

In addition to the technical program, we are pleased to offer post-conference excursions in Shanxi Province, China, with visits to the Datong Volcanic Cluster, the Jinhua Palace Coal Mine, the Yungang Grottoes, and the Antaibao Open Pit Mine. These excursions will provide an excellent opportunity to examine representative coal-bearing successions, major mining operations, and distinctive volcanic landforms, while further strengthening communication and collaboration among participants.

We wish you a productive, inspiring, and memorable TSOP 2026 in Beijing. Welcome to Beijing, and we look forward to seeing you!

The Organizing Committee for the 42^nd Annual Meeting of TSOP
