Why laterite not calcareous?

Ravindra said: (Jun 27, 2015)  
Because laterite is argillaceous rock.

What is Macl?

I am not satisfied with the answer because "clay" is also argillaceous rock.

Sujeet said: (Jun 9, 2017)  
The mineralogical and chemical compositions of laterites are dependent on their parent rocks. Laterites consist mainly of quartz, zircon, and oxides of titanium, iron, tin, aluminium and manganese, which remain during the course of weathering.

What is Macl?

Maybe it's Marls (argillaceous limestone).

Yes, laterite is an argilliceous rock.

In calcareous rock, lime is the main constituent and argillaceous rock have clay.
