Abstract
The Jezero crater is located in the Nili Fossae region of Mars with a 45-km diameter. Since the Jezero crater has a fan-delta deposit rich clays, it was one of the sites considered for in situ exploration by the Mars Science Laboratory. The Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) aboard the Mars Reconnaissance Orbiter (MRO) is a visible and near infrared spectrometer with enhanced spectral resolution, which provides the ability to map the detailed and large-area the minerals on Mars. In this paper, Using spectral angle mapper (SAM) based on the CRISM near-infrared spectral data, minerals and rocks components at Martian Jezero region are recognized in details. The dominated minerals in Jezero Crater are silicate and carbonate minerals. Silicate minerals include pyroxene, actinolite, and hornblende, while carbonate minerals include ankerite, calcite, siderite and northupite. These minerals suggest that the Jezero Crater has experienced the sedimentation and metamorphism.
