Abstract
Some soils under tropical forests in western Thailand are derived from skarn complexes of hydrothermally metamorphosed granitic, calcareous and ultramafic rocks. We used data from six large, long-term forest ecological research plots to compare the soils derived from skarn with forest soils derived from granites and sedimentary parent materials elsewhere Thailand. The soils derived from skarn are Vermic Phaeozems and have deep, dark, worm-worked topsoils and bimodal particle size distributions of coarse sand and grit in clay or fine loam matrices. They are eutrophic with respect to both labile and non-labile forms of the mineral nutrients. The soils derived from other parent materials are mo..

We are grateful to many colleagues for assistance in the fieldwork and data processing, particularly the forest inventory teams at Huai Kha Khaeng and Khao Chong. All of the plots are maintained by the National Parks Wildlife and Plant Conservation Department of the Royal Government of Thailand. The 50 ha plot at Huai Kha Khaeng and the Khao Chong plot are part of the Center for Tropical Forest Science (CTFS) pantropical network and receive financial assistance from the Arnold Arboretum of Harvard University (USA), Smithsonian Tropical Research Institute (USA), National Institute for Environmental Studies (Japan), National Science Foundation (USA) (Grant DEB. 0075334) US-AID (USA), Rockefeller Foundation(USA), and the John D. and Catherine T. McArthur Foundation, (USA). The plots at Huai Krading, Kapook Kapieng, Mae Ping and Chiang Dao are wholly resourced by the Royal Government of Thailand. PJB's fieldwork was supported by grants from the Lockwood Fellowship, National Science Foundation, and Sigma Xi. IB's fieldwork was funded by a Bullard Fellowship from Harvard Forest and a travel grant from CTFS.
