According
    to physical characteristics of rocks and minerals, both the geophysical models
    and the exploration indicators in search for chromite were established. The
    composite characteristics of gravity and magnetic anomalies seem to be
    indicators identifying chromite. In addition, the authors utilized the
    approaches including the wavelet analysis method to extract the local gravity
    and magnetic anomalies generated by chromite and ultramafic rocks, employed the
    tilt-angle method to identify rock boundaries, applied Paker method to density
    mapping, and also used interactive 2.5D inversion method. It is also pointed
    out that the chromite exploration in Tibet requires not only high-precision
    field measurement but also careful indoor data processing and interpretation.
