Simulant Name: CUG-1A Chinese University of Geosciences
Current Status: Unknown
Developed By: Chinese University of Geosciences, Wuhan
Available From: N/A
Publications: He, X. X. et al. (2010), Lunar Regolith Simulant CUG-1A. 41st Lunar and Planetary Science Conference, Abstract #1183.

CUG-1A is a geotechnical lunar mare simulant developed at the Chinese University of Geosciences at Wuhan. It is described in a single conference abstract by He et al. The simulant was made from basaltic volcanic scoria from Huinan County in northeast China and is chemically similar to Apollo 14 soils.

The scoria was ground and sieved into different size fractions that were then re-combined to achieve the desired particle size distribution. He et al. (2010) claim that several hundred kilograms were produced, but it is unclear what the current status of the simulant is.
