Based on petrochemical studies, Mahadeva is classified as H-chondrite. Homogeneous olivine (Fa:19.3 mol%) (percent mean deviation &lt;4%) and low-Ca pyroxene (Fs:17.6 mol%) composition further suggest that Mahadeva is highly equilibrated chondrite (resembles petrologic type 5\/6), a few relict chondrules still can be recognised. The temperature of equilibration is estimated \u223c800\u00b0C with evidences of moderate shock metamorphism (S2-3, St\u00f6ffler et al., 1991). Bulk chemical composition is also consistent with the mean H-chondrite. The cosmogenic radionuclides activities are found to be consistent and match with the production rate and solar cycle activity.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dipak K.
