Describe the megascopic and microscopic characters of gabbro and basalt with help of neat well labelled diagrams.

Gabbro and basalt are two types of mafic igneous rocks composed primarily of silicate minerals, and they share a similar chemical composition, mainly consisting of feldspar, pyroxene, and olivine. However, they differ in their texture, mineral composition, and formation environments. The differences between these two rocks can be analyzed through both megascopic (visible to the naked eye) and microscopic (under a microscope) characteristics.

### Megascopic Characters of Gabbro and Basalt

Gabbro is a coarse-grained igneous rock, meaning that its crystals are large enough to be seen without a microscope. The rock is typically dark in color, ranging from dark gray to black, due to its high iron and magnesium content. The mineral grains in gabbro are usually visible to the naked eye and are typically interlocking, which gives the rock a rough texture.

- Texture: Gabbro displays a phaneritic texture, where all the mineral grains are large enough to be observed _____ ____ __________ __________ ______ _________ ______ __________ ______ _____ ________ ______.
