DescriptionTroctolite76535.jpg	Troctolite sample 76535 brought back from the Moon by Apollo 17. This sample has a mass of 156 grams and is up to 5 centimeters across. It was collected as part of a rake sample at station 6 at the foot of the North Massif. Another view of this sample was used in Figure 7-16 of the Apollo 17 Preliminary Science Report (SP-330, 1973), which has the following caption: Coarse-grained norite (sample 76535) with fresh-appearing plagioclase (white to light gray) that has typical striations of albite twinning. Although pyroxenes (medium gray) are fractured along cleavage planes, they do not appear badly crushed.
