The Vega 2 lander determined the composition of rock in the area of the northern slope of the high-mountain massif Aphrodite Terra, which had never previously been analyzed. The rock was analyzed by X ray fluorescence analysis employing instrumentation similar to that on Venera 13 and 14. The abundances of the major rock-forming elements from Mg to Fe, inclusively, and also upper limits for some heavier rare elements, were determined. Comparison of these data with analyses of terrestrial rocks enables the authors, with certain reservations, to suggest that the analyzed Venusian sample is olivine gabbro-norite.
