Columnar Basalt and Trap Rock quite different[edit]

I would like to see an article for trap rock kept separate from basalt in general. For one, not all trap rock is basalt, let alone columnar basalt. Trap rock is manifest in three forms: basalt (which is usually extrusive), diabase (which is always intrusive), and hornfels (which can be formed at the surface or in an intrusive setting). Additionally, trap rock can exhibit any of the following qualities: stacked, jointed, or columnar.

In a nut shull, 'trap rock' is just another way of describing most blocky volcanic rocks. It has particular relevance to quarrying since trap rock in its varying forms is crushed to make road and railroad beds. lithium6ion (talk) 22:18, 9 August 2009 (UTC)[reply]

Proposed merge of Traprock mountain into Trap rock[edit]

Substantial overlap between the two pages. Traprock mountain, in its own words, is generally about "landscape features" made of trap rock, not just mountains. It's not clear why mountains would need their own page anyways. The "Notable landforms" section could be used to expand the "Examples" section here.

WP:SILENCE, so did the merge. Some of the added examples aren't mentioned as being traps on their pages and might need references added. Apocheir (talk) 22:05, 21 November 2022 (UTC)[reply]
