Since only a small area surrounding the intrusion is heated by the magma, metamorphism is restricted to the zone surrounding the intrusion, called a metamorphic or contact aureole. Outside of the contact aureole, the rocks are not affected by the intrusive event.ataclastic metamorphism occurs as a result of mechanical deformation, like when two bodies of rock slide past one another along a fault zone. Heat is generated by the friction of sliding along such a shear zone, and the rocks tend to be mechanically deformed, being crushed and pulverized, due to the shearing.
If you suffer from hay fever and youâve ever experienced an itchy mouth or scratchy throat after eating certain raw fruits or vegetables and some tree nuts, you may have oral allergy syndrome symptoms.
To be more specific, the smaller your jaws, the more likely you'll sleep poorly when you have allergies. Even if you're completely normal, having a stuffy nose can suddenly cause your tongue to fall back and block your breathing. Plugging your nose has been shown to cause obstructions and arousals during sleep. This is why you'll toss and turn when you have an allergy or a simple cold. Many people with allergies and small mouths will also have grooves or indentations along the side of their tongues. This is called tongue scalloping.
