High Calcium Pyroxene (HCP) Norbert Brügge, Germany Clear text: Apparently the specialists who work for NASA are still not clear what kind of igneous rocks it is and what its composition is. But it was clear from the beginning that olivine and hornblende would predominate. So far not a word about the large hornblende crystals. The occurrence of High Calcium Pyroxene (HCP) in the groundmass is only hesitantly admitted. The igneous rocks are not a lava flow, but belong to an eruption of ultramafic mantle magma (not dunite). The tectonic disturbances of this magmatic rocks are also ignored. The paradigm of a paleolake in the Jezero crater says goodbye slowly. As expected, the instruments carried are not able to identify minerals. The statements published so far are only assumptions and also confused. Unfortunately for the trash (below).

in "South Seitah" (sol-292) clearly shows the main components in the groundmass:
The white HCP crystals have now been detected in 9 abraded spots and 8 drill cores
