Basalt with Peridotite Nodule
Basalte avec nodule de péridotite facilitates the direct analysis of upper mantle composition, allowing students to evaluate the physical state of the Earth's interior at secondary and university levels.
Microcrystalline Basaltic Matrix Supports the identification of rapid cooling textures in oceanic and continental crust modeling, aiding in the application of thermodynamics to igneous petrology.
Visible Mineral Boundaries (Xenocrysts) enable students to synthesize data regarding the speed of magmatic ascent and the mechanical transport of mantle fragments to the surface.
High-Density Surface Preparation Optimized for hand-lens and binocular microscope observation, facilitating accurate student readings of crystal morphology and mineral habit.

Basalt with Peridotite Nodule This basalt specimen containing a peridotite nodule lets students study upper-mantle mineralogy directly, since the nodule is a fragment of mantle rock carried to the surface by rising magma.
Basalt with Peridotite Nodule is priced at approximately ₹430 (indicative market benchmark, incl. GST, August 2026).
Product Description
This basalt specimen contains an embedded peridotite nodule, a fragment of upper-mantle rock that was carried to the surface within rising magma. Because the nodule offers a direct sample of mantle material, this dual-lithology specimen supports petrographic analysis of olivine and pyroxene minerals typically found in mantle xenoliths, alongside the surrounding basaltic host rock. This makes it a valuable specimen for university and vocational earth-science coursework studying magma ascent and mantle composition.
