green balls in rock, id help

[alan p]

Found this rock by accident on a beach, I used it to break open rusty lumps ?, rock broke open in my hand and I noticed the green and white spots and balls, any ideas, I've been on meteorites site as thought maybe olivine chondrules, the white spots are green underneath, the matrix is a dull brown with a brighter glassy brown rock blended in, the green balls look like an addition to the main mass, lots more green spots under microscope, cannot find anything similar looking only meteorites

Looks like olivine crystals in an igneous background.

Jim might be right. Some kind of variation of zeolite is also possible.
