No. Lava is magma that has reached the surface. It isn't even technically a rock until it has cooled, and when it does, it is extrusive igneous rock.

Granite is commonly classified as an igneous rock, one that was formed from cooling magma below the surface of the earth (intrusive). Igneous rock formed from lava erupted at the earth's surface like basalt are called extrusive.

Neither of these rocks would be called organic as they were not formed from things that were once alive. Coal could be called organic as it was formed originally from plant material.

Chemistry is typically divided into Organic and Inorganic and in this sense, Organic refers to reactions involving the element Carbon.

Organic is a term also used in connection with food, where it is generally used to refer to food grown or produced without use of pesticides or artificial fertilisers

Rocks are categorized into three distinct types based on their method of formation. The three types are igneous, sedimentary, and metamorphic. Early in Earth's history, all rock was igneous, having formed from the cooling of melt on the surface.

An igneous rock is simply a rock that has solidified from magma or lava upon cooling. Igneous rocks can be intrusive (solidified from magma underground) or extrusive (solidified from lava at or near the surface). The bulk of Earth's crust is formed from igneous rock. Examples of igneous rock include basalt, obsidian, rhyolite, granite, diorite, gabbro, and pumice.

A sedimentary rock is one that is formed by the accumulation of small to large sediment particles derived from all three types of rock and in some cases organic material, and undergoes compaction, cementation, or evaporation from/precipitation from a saturated mineral solution. Sedimentary rock is classified as organic, (derived from organisms), clastic (formed from any size particle of preexisting rock), or non-clastic (also referred to as chemical), where the sedimentary rock is formed from the evaporation of a solution that is saturated with mineral compounds. Examples of organic sedimentary rocks are coal and limestone. Examples of clastic sedimentary rocks are conglomerate and shale. Examples of non-clastic or chemical sedimentary rocks are rock gypsum and rock salt.

A metamorphic rock is an igneous, sedimentary, or another metamorphic rock that has either been squeezed by incredible pressures deep underground and/or has been exposed to very high temperatures, altering its structure, mineral alignment, or chemical composition. Metamorphic rocks are classified as contact (from proximity to a magmatic intrusion) or regional (resulting from deep burial and pressures from plate collisions Metamorphic rock is also classified as foliated or non-foliated, foliation being the parallel alignment of the constituent minerals in bands that are perpendicular to the applied pressure. Metamorphic rocks can also be described by the grade of metamorphism which has taken place from low to high, high being the closest to the next stage in the rock cycle, melting. Examples of metamorphic rock are slate, quartzite, marble, phyllite, schist, and gneiss..

The three major types of rocks are sedimentary, metamorphic, and igneous.

Metamorphic rock must first turn into sediment through uplift, weathering, erosion and deposition before the sediments can undergo lithification and become sedimentary rock. Further compaction, pressure, and heat can turn it into metamorphic rock. In order to change into igneous rock it would need to be buried so deep in the earth that the heat partially melts the metamorphic rock forming magma. Then the magma would need to ascend, cool, and undergo recrystallization to form igneous rock.

Minerals. Metamorphic minerals like sillimanite, kyanite, staurolite, andalusite, and garnet, and non-metamorphic minerals like olivines, pyroxenes, amphiboles, micas, feldspars, and quartz.

Through weathering and erosion of the metamorphic rock. The metamorphic rock, exposed to weathering processes at the surface, breaks into smaller pieces. Erosional processes transport these pieces to a place of deposition where they build up, layer on layer. Eventually the compaction caused by the weight of the sediments above reduces the amount of space and water between particles. In this process of rock formation known as lithification, cementing minerals are formed out of the slowly disappearing fluids, which are saturated with mineral components. Once cemented together, it is now considered sedimentary rock.

Metamorphic rocks may display foliation, which is the layering, banding, or platiness that is associated with the rearrangement of mineral crystals due to directional pressure. Examples of foliated metamorphic rock include schist, slate, and gneiss.

Some minerals are typically formed due to the metamorphism of existing rock, and include those minerals that form due to the loss of water. When minerals that contain water can no longer exist due to heat and pressure, new minerals form. Garnet is a non-hydrous mineral that is often associated with metamorphic rock.

Metamorphism in rock can also manifest itself by the replacement of existing minerals by other minerals due to the invasion of the host rock by heated fluids which are created by a nearby magmatic intrusion.

Metamorphic rocks can also display a recrystallization and interlocking crystalline structure that is common when limestone or dolostone is metamorphosed into marble, or sandstone is metamorphosed into quartzite.

Geologists categorize rocks into three basic groups, of which sedimentary and metamorphic are two. Igneous is the third. Sedimentary rocks are laid down in layers of sediments such as mud, silt and sand that accumulate and harden over time. Igneous rocks are formed from the solidification of lava or magma. Metamorphic rocks are a bit of a combination. They are sedimentary rocks or igneous rocks that have been deformed and changed by high pressure and temperature deep in Earth, or by contact with, or close proximity to a magmatic intrusion.

A simple diagram showing the rock cycle with the processes that link sedimentary and metamorphic rocks as well as a simple diagram showing how metamorphic rocks are named and the rock types from which they are formed as well as A glossary of geological terms is also available.

Igneous rocks, such as granite, when subjected to extreme pressure and temperature will change to metamorphic rock. Evidence that an igneous rock had undergone metamorphism would include light and dark mineral banding; possibly with indications of partial melting in highly metamorphosed samples.

Sedimentary rock becomes metamorphic rock through the addition of heat and/or pressure. Contact metamorphic rocks are those primarily transformed by close proximity to an intrusion of magma, where a recrystallization or elemental transfer can take place. Sedimentary rocks like shale can metamorphose into slate mainly through pressure and heat derived from plate collision, where the alignment of minerals is changed resulting in a foliated texture.

Metamorphic rock really is found deep underground, at the base of mountains, in zones radiating from intrusions of magma underground, on glaciated terrain after transportation by ice, or on the surface of eroded mountains.

Everywhere at some depth, and on the surface where uplift and erosion have allowed them to be visible. They can also be found as pebbles or boulders in glacial drift, deposited in areas in which they do not normally appear.
