There are no specific drainage patterns that only form on massive igneous rocks. Drainage patterns are largely determined by the underlying geology and the slope of the land.

However, there are certain types of drainage patterns that are commonly found on volcanic or igneous landscapes. For example, dendritic drainage patterns, which resemble the branching pattern of a tree, are common on volcanic landscapes that have undergone extensive erosion.

Rectangular drainage patterns, which are characterized by channels that follow a rectangular or orthogonal pattern, can also be found on volcanic landscapes that have been faulted or fractured.

Parallel drainage patterns, which occur when streams flow parallel to each other, can also be found on volcanic landscapes that have undergone extensive faulting or fracturing.

Ultimately, the specific drainage pattern that forms on any given landscape is determined by a variety of factors, including the underlying geology, the slope of the land, and the climate and vegetation of the area
