Natrolite
Natrolite is Na₂Al₂Si₃O₁₀.2H20
Natrolite is a member of the zeolite family of silicate minerals.  It is a hydrous sodium aluminum silicate.  As seen in the following photo, natrolite forms clusters of delicate radiating needle-like crystals.  Natrolite is a secondary origin mineral commonly found in filling gas pockets (amygdules) in basalt.
