Khon Kaen Geopark, representing an area of dinosaur fossil diversity, was selected for investigations to reveal the origin and tectonic setting of the Khorat Group. The area occupied by Mesozoic sedimentary rocks of four formal formations of the Khorat Group, namely the Phra Wihan Formation (PWF), Sao Khua Formation (SKF), Phu Phan Formation (PPF), and Khok Kruat Formation (KKF). A field investigation and macroscopic observations suggested that the immature sedimentary rocks of the study area are mainly clast-supported, pebbly sandstone and siltstone with few calcretes.

Field investigations and classification suggest that paleontological sites present the first dinosaur species in Thailand and confirm the existence of five dinosaur species: , , , , and . The geomorphological sites feature representative sandstone landforms, including waterfalls, cliffs, caverns, honeycombs, pedestal rocks, and rugged surfaces with irregular features.

- Lava Durian Sisaket is the first geographically identified fruit from volcanic origins in Thailand, specifically within Sisaket Province, known for its unique basaltic soil derived from volcanic rock.
- The study explores the lithology, mineralogy, and geochemistry of the basaltic rocks in the orchards, utilizing various techniques to analyze the soil and rock characteristics.
- Findings indicate that the local basalts are rich in minerals, particularly olivine and nepheline, and have undergone significant alterations, contributing to the fertile nitisal soil beneficial for agriculture in the region.
This data article presents mineralogical and geochemical data of high alkaline basalts in Sisaket province, the southern part of Khorat Plateau, NE Thailand. Under the polarized light microscope, the photomicrographs divided the basalts into olivine basalt and alkaline basalt with four textures: aphanitic, porphyritic, vesicular, and diabase. These basaltic rocks comprise olivine microphenocrysts associated with labradorite-anorthite (An), clinopyroxene, opaque minerals groundmass.
