Many masses, individuals up to 20kg, of total weight about 80kg, were found in the Chinga stream, a tributary of the Upper Yenisei from the Tanno-ola Mts. Recognised as meteoritic,The place of fall is incorrectly mapped. Analysis, 16.38 %Ni, 0.181 ppm-Ga, 0.082 ppm,Ge, 3.6 ppm.Ir,. Many of the specimens are strongly oxidised, and some have the torn appearance characteristic of fragments from meteoritic craters such as Canyon Diablo and Henbury. It is thought probable that this fall was associated with a crater that has disappeared through erosion, or perhaps has simply passed unnoticed, but fieldwork in 1963 failed to find any crater, Fragments of metal with 16.37%Ni, found in the alluvium of the upper Argolik river, Tuva district are now attributed to the Chinga fall.
