Diabaas is indeed a type of stollingsgesteente, but there are other options with seven letters. Here are a few examples:
- Graniet (Granite): A common igneous rock known for its coarse-grained texture and durability.
- Gabbro (Gabbro): A dark-colored igneous rock often found in oceanic crust formations.
- Basalt (Basalt): A volcanic rock with a fine-grained texture, commonly forming lava flows.
The specific type of stollingsgesteente depends on its mineral composition and cooling history.
