Why is granite so durable?
Tuesday 04 January, 2022
News Brief

Dear Spaggs,

Why is granite so durable?
Our resident geologist says that the durability of granite comes down to its mineralogical structure, which can only be effectively seen when magnified.

No wonder granites are the preferred option for railway track ballast,and for high-end architectural use.

Full Story:

The durability of granite comes down to its mineralogical structure, which can only be effectively seen when magnified.

It is possible to cut slices of rock using a diamond saw, and then polish them so thinly that light will pass through the constituent particles when viewed under a microscope.

Our image shows such a “mineralogical slide” of silver grey granite photographed through a microscope. This clearly demonstrates how each individual mineral grain is interlocked and almost fused with its neighbour. It is this structure which makes granite so durable as there are, no easily distinguishable fracture planes, further, the tight packing of the constituents prevents in ingress of water and damaging frost.

No wonder granites are the preferred option for railway track ballast, with large quantities of the rock being quarried for this purpose in Leicestershire, Scotland and North Wales.
