Quartz/feldspar fragment (‘clast’) sizes were measured in thin sections of three types of fault zone rocks, e.g., melting-dominated pseudotachylyte (M-Pt), crushing-dominated pseudotachylyte (C-Pt) and cataclasite (Ct), from two well-studied Precambrian shear/fault zones in the Indian craton (e.g., the Gavilgarh–Tan Shear zone in central India and the Sarwar–Junia Fault zone in western India). Logarithmic plots of clast area
$\bullet$ Clast size and cumulative frequency were measured in pseudotachylyte and cataclasite samples from two shear zones.
$\bullet$ Size-frequency relationship follows a power law in melting- and crushing-dominated pseudotachylytes.
$\bullet$ The power law does not hold good for the finest and coarsest size ranges in both types of pseudotachylytes.
$\bullet$ For cataclasite, a multi-fractal power law relationship exists between the size and cumulative frequency of clasts.
