No. I believe they are called chemical precipitate sedimentary rocks. Yes, I'm sure they're called that. Absolutely! Porphyritic is a term usually applied to igneous rocks, having to do with mineral formation and rock texture.
Clastic Sedimentary Rock- Sedimnetary rocks formed from fragments of rocks cemented together by minerals such as calcite.Chemical Sedimentary Rock- Sedimentary rocks formed from a solution of minerals (such as halite) and water.Organice Sedimentary Rocks- Sedimentary Rocks formed from the remaints of dead sea animals and seashells.

sedimentary rock that forms when minerals crystallize from a solution
Clastic sedimentary rock forms when fragments of preexisting rocks are compacted or cemented together. Organic sedimentary rock forms from the remains of plants or animals. Chemical sedimentary rock forms when minerals precipitate from a solution or settle from a suspension.
When minerals crystallize from a solution
They are classified as clastic or non-clastic. Clastic sedimentary rocks are formed from rock particles of various sizes. Non-clastic rocks are formed from precipitation of minerals out of solution or by the lithification of organic matter.
These minerals are called evaporites.
Chemical sedimentary rocks form by precipitation of minerals from water. Precipitation is when dissolved materials come out of water. For example: Take a glass of water and pour some salt (halite) into it. The salt will dissolve into the water.
They would be referred to as chemical sedimentary rock.
Evaporation of a solution containing certain minerals may cause those minerals to crystalize, forming a solid.

Evaporite minerals are minerals found in sedimentary rocks that are formed as precipitates from the evaporation of a saline solution. A diapir structure formed by evaporite minerals is a salt dome.
