How do the sequences of sedimentary rocks in cratons differ from those in mountain belts?
The sequences of sedimentary rocks in cratons are typically thin and are relatively undeformed or gently warped. The sequences in mountain belts, meanwhile, are thick and extensively folded and faulted.
What are the ancient continent cores called?
Areas of ancient continental interiors are called cratons.
Do cratons contain diamonds if so how do they get there?
According to Wikipedia, a craton is an "...old and stable part of the continental lithosphere" -- the earth's outermost rocky shell. Kimberlite pipes, where diamonds are commonly found, are sometimes rooted in cratons. You can read more by following the link, below.
What is the geologic name of the areas with the least amount of earthquake activity?
Cratons, large geologically stable areas in continental interiors.
Why is only a portion of the North American craton is visible?
Platforms and shields together make up cratons. The shield is the part of the craton that is exposed at Earth's surface and the platform is the part of the craton that is covered by sedimentary strata.
What do cratons do?
Cratons contain the ancient crust of igneous rocks.
The ancient continent cores are called?
cratons
What areas are dimonds mined from?
Old Continental cratons with diatremes or in sediments derived from such.

Where on earth are diamonds normally found?
In old areas of continental crust called "cratons" in volcanic structures called "kimberlite pipes".
What are some facts about interior plains?
It was formed when cratons collided and welded together.I dont know if he is right but i think that he is really good I dont know what it means.
Can diamonds form without kimberlike pipes?
Since diamonds are most rare, indicator minerals are the only way to predict -- sometimes unsuccessfully -- where a miner might locate diamonds.The pipes are always required, since that's how diamonds are pushed up to the surface from earth's upper mantle, and kimberlite is not the only indicator mineral. (Link, below.)Diamond formation does not occur in the pipes: it occurs in cratons. From Wikipedia:"The correct combination of temperature and pressure is only found in the thick, ancient, and stable parts of continental plates where regions of lithosphere known as cratons exist. Long residence in the cratonic lithosphere allows diamond crystals to grow larger."You can read more about cratons, below.
What has the author Henry V Lyatsky written?
Henry V. Lyatsky has written: 'Principles of practical tectonic analysis of cratonic regions' -- subject(s): Cratons, Structural Geology
