This rock appears to be a type of igneous rock known as vesicular basalt. Here's why:

Texture and Appearance: The rock has a porous, hole-filled (vesicular) texture, which is characteristic of basalt that has cooled quickly from lava, trapping gas bubbles as it solidifies. These holes or vesicles are where gas escaped or was trapped during the rapid cooling process.
Color: The green color suggests the presence of iron oxides, which can give basalt this hue, especially if it has been weathered or oxidized.
Formation: Basalt is an extrusive igneous rock, meaning it forms from lava that erupted onto the Earth's surface. The rapid cooling of lava at the surface causes the formation of small crystals, and if the lava contains gas, it can form vesicles as seen in the rock.

This type of rock is common in volcanic regions and can be found in lava fields or near volcanic vents. If you're interested in a more precise identification or if you want to explore its mineral content, consulting with a geologist or using advanced analytical techniques like X-ray diffraction would be beneficial.This rock appears to be a type of igneous rock known as vesicular
