Intrusions Home Thoughts: They further defined this as a part of the more general right to "the immunity of the person the right to one's personality." This doctrine, which was revolutionary in its time, restrains unwarranted intrusions home thoughts into home and thoughts and dreams. It is our hope that the law will use it in the future to restrain equally any intrusions home thoughts, whether by the state or by organizations of scientists, into the free development of the human personality.
Contact Metamorphism.—Igneous intrusions home thoughts cool by the conduction of heat through their walls, and in cooling increase the temperature of the enveloping rocks. Thus intrusions home thoughts are generally surrounded by contact metamorphic aureoles, or areas where heat from the intrusion has metamorphosed the country rocks.
Metamorphic rocks are usually much harder than sedimentary rocks. Some are formed by deep burial, others by the heat of igneous intrusions home thoughts. Their grains are all interlocking crystals and many, such as slates, schists and gneisses, split easily along certain planes.
Others, such as quartzite and marble, are compact rocks which break in any direction.
When sedimentary rocks are intruded by a molten mass of magma they are altered. This process is a form of metamorphism known as thermal or contact metamorphism. Small intrusions home thoughts such as dikes and sills merely bake a thin skin of rock and make it harder; large intrusions home thoughts, such as the Dartmoor (southwest England) granite, alter the rock for several miles around. A large intrusion may heat the rock to 700°C (1,292'F) and take more than a million years to cool, giving time for new minerals to form. |
