marlstone

The marlstone is typically a firm, greyish limestone weathering to a rusty brown colour, and is always more or less argillaceous.

I returned to Marlstone, and faced your friend the detective with such nerve as I had left.

Dr. Stock, of Marlstone, was at once sent for, and will conduct the post-mortem examination.

You will perhaps remember that we met, under unhappy circumstances, in June of last year at Marlstone.

This slaty marlstone is richly impregnated with copper pyrites, for which it is extensively worked.
