Paper Title
The Quaternary Sandstorm in Muang, Nakhon Ratchasima, Northeastern Thailand - Evidenced from the Aeolian Sediment

Aeolian sediment in the southern part of Muang Nakhon Ratchasima was studied for its grain size analysis to explain the mode of transportation and the depositional environment. Three samples of bottom, middle, and top intervals were collected from four studied sites, Nong Kung, Nong Pling, Ang Hin Hua, and Phu Khao Thong villages.The major grain size is very fine-grained to medium-grained, showing a coarsening upward trend in all sites, suggesting the saltation movement with increasing wind energy. The estimated wind speed would exceed ten m/s, the initial speed of a sandstorm, and occurred in one event during the Quaternary Period.
