Quarry Marks: (Construction Techniques) The megalithic builders employed the same method of splitting quartz, at different locations all around the world. This is not unusual, as it is probably the best method, and is still widely used today.
In these methods, blocks of rocks are broken loose from their natural outcrops by men using hand tools or special purpose channeling machines. No explosive material is used at any stage in this method of quarrying of stones. Soft rocks and also those rocks which have layered structure are easily quarried by these methods.

Even from a distance, you can hear quarrying equipment grinding rocks. The crushing jaws are cracking the quarried material while the deposited stones are conveyed to a screening station. Sorted and classified, the different flinty pebbles are stacked, loaded, and dispatched. Back at the dusty processing line, different quarrying methods are in action.
In other words a quarry is a big manmade hole in the ground from where minerals or rock are taken out.
