A tentative discussion on the variation of selenium isotopes in black shale of Niutitang Formation,Zunyi,Guizhou Province,and its implications for depositional environment;

A discussion on Mo isotopic compositions of black shale and Ni-Mo sulfide bed in the early Cambrian Niutitang Formation in south China;

Geochemical Characteristics and Formation Environment of the Niutitang Formation in the North Guizhou;

Sasaite from Niutitang black shales at Zunyi occurs mainly as micro-fissures in Ni-Mo multi-metal mineralization strata, and also as small sasaite veins in black shales beneath the Ni-Mo multi-metal mineralization strata.

The Niutitang Biota from the lower Cambrian in Songlin Town, Zunyi County, Guizhou Province, southwestern China is dominated by sponges and represents early radiation of sponges in early Cambrian.

The early Cambrian Niutitang Biota from Guizhou abounds in sponges (Zhao et al .

Three-dimensional geometrical modeling of the exterior configuration of a cattle hoof by reverse engineering technology;

Because on the characteristics of the buffalo hoof are suitable for walking on the paddy-field and soft soil,reverse engineering technology was used to extract the features for low walking resistance based on which the bionic blade for the paddy field impeller is designed.
