The Nanjing Geological Exhibition Hall, located in Nanjing City of Jiangsu Province, is a local comprehensive museum of geological science of China. It used to be the Geological and Mineral Exhibition Hall affiliated to Beiping Geological Survey Institute. In 1935 it was moved to Nanjing. The new hall built in August 1935 was named the Nanjing Geological and Mineral Exhibition Hall. In 1937 before Nanjing fell into the hands of the Japanese aggressors it was moved to Chongqing. Three geological and mineral exhibitions were held in Chongqing to show the new achievements of the geological work during the War of Resistance Against Japan (1937-1945) with the newly excavated Lufeng Dinosaur fossil among the exhibits. In June 1946, the Nanjing Geological and Mineral Exhibition Hall was moved back to Nanjing and in 1952 it was renamed Nanjing Geological Exhibition Hall.

The Nanjing Geological Exhibition Hall has collected more than 20,000 items of collection, including Wang's Yunnan Dinosaur fossil, the Chinese Sinian hornblende, corundum precious stones (ruby and sapphire), diamond, crystals,yuhuapebbles (colorful fine-grained pebbles found in the Yuhuatai area in Nanjing), agate, jadeite, nephrite, andjixueshi(bloodstone),Qingtianstone (stone from Qingtian County in Zhejiang Province, used to make seals).

The Nanjing Geological Exhibition Hall covers a space of 1,600 square meters, arrayed with twelve exhibition rooms such as the ordinary geology, petrology, mineral products, precious stone minerals, the geology and minerals of Jiangsu Province, stratum paleontology, dinosaur, the paleovertebrateof the Neolithic Age and paleoanthropology. On display are 6,000 pieces of various kinds of analogical and mineral samples, models and plates. The exhibits include ideal model of trace features and special cupboard of trace fossils,the special cupboard of the third survey to the Antarctic Pole, the large-scale scene box telling about dinosaurs and their ecological environments and the material objects and models of the evolution of paleoanthropic man. The Nanjing Geological Exhibition Hall has also sponsored temporary exhibitions such as the Achievements of the Urban Geological Work in Jiangsu Province and the Geological Calligraphies and Paintings.

The scientists of the Nanjing Geological Exhibition Hall have obtained important achievements in scientific researches. In 1983, they found the fossils of three new species of ape, Wang's Shangxin ape, Tian'ganghu gibbon and Sihong forest ape from the Miocene Epoch stratum at Tian'ganghu Township of Sihong County in Jiangsu Province. Irregularly, the Nanjing Geological and Mineral Exhibition Hall also sponsors various kinds of activities, such as lectures on special topics, slides show or video show and scientific summer camps for youngsters during the summer vacation every year.
