Jade
There are two distinct minerals commonly known as Jade: Nephrite (a calcium magnesium silicate - Ca2(Mg,Fe)5Si8O22(OH)2) and Jadeite (a sodium aluminum silicate - NaAlSi2O6). Based on the image showing a typically softer, more fibrous appearance, it is likely Nephrite.

Gneiss (specifically, a variety exhibiting prominent banding; mineral composition can vary, but often contains quartz, feldspar, mica, and amphibole)
Metamorphic Rock
Dark Igneous Rock (Likely Basalt or Diabase)
Basalt (extrusive igneous rock) or Diabase (intrusive igneous rock - also known as Dolerite), largely composed of plagioclase feldspar, pyroxene (augite), and sometimes olivine and amphibole. Exact mineralogy would require thin section analysis.
