Natural Fibrous Rock Specimen - Mineral Sample for Geology & Education #123404 (License: Personal Use)

This specimen displays a coarse, interwoven fibrous structure typical of certain metamorphic or volcanic rocks, such as asbestos-bearing serpentinite or fibrous amphibole. Its dark gray matrix is interspersed with lighter, thread-like mineral fibers, giving it a distinctive matted appearance. The irregular, angular shape suggests minimal processing, preserving its natural form for scientific observation.

Used in geology textbooks, museum exhibits, online mineral databases, and educational platforms to illustrate rock textures, mineral composition, and formation processes; targets students, educators, collectors, and researchers.
