"Net-textured sulfide"s (Canada) or "matrix sulfide"s (Australia) are composed of 30-50% sulfide interstitial to olivine (typically serpentinized), which have been interpreted to have formed by static gravitational segregation, dynamic flow segregation, or capillary infiltration. This texture is well preserved in many areas (e.g., Alexo, Ontario; Kambalda, Western Australia; Raglan, New Quebec), but in high-grade metamorphic areas it has been replaced "jackstraw texture", composed of bladed to acicular metamorphic olivines, which superficially resembles spinifex textured olivines, within a matrix of Fe-Ni-Cu sulfides.
