1. Sill

   In geology, a sill is a tabular sheet intrusion that has intruded between older layers of sedimentary rock, beds of volcanic lava or tuff, or even along the direction of foliation in metamorphic rock. The term sill is synonymous with concordant intrusive sheet. This means that the sill does not cut across preexisting rocks, in contrast to dikes, discordant intrusive sheets which do cut across older rocks. Sills are fed by dikes, except in unusual locations where they form in nearly vertical beds attached directly to a magma source. The rocks must be brittle and fracture to create the planes along which the magma intrudes the parent rock bodies, whether this occurs along preexisting planes between sedimentary or volcanic beds or weakened planes related to foliation in metamorphic rock. These planes or weakened areas allow the intrusion of a thin sheet-like body of magma paralleling the existing bedding planes, concordant fracture zone, or foliations. Sills parallel beds and foliations in the surrounding country rock. They can be originally emplaced in a horizontal orientation, although tectonic processes may cause subsequent rotation of horizontal sills into near vertical orientations. Sills can be confused with solidified lava flows; however, there are several differences between them. Intruded sills will show partial melting and incorporation of the surrounding country rock. On both contact surfaces of the country rock into which the sill has intruded, evidence of heating will be observed. Lava flows will show this evidence only on the lower side of the flow. In addition, lava flows will typically show evidence of vesicles where gases escaped into the atmosphere. Because sills generally form at shallow depths below the surface, the pressure of overlying rock prevents this from happening much, if at all. Lava flows will also typically show evidence of weathering on their upper surface, whereas sills, if still covered by country rock, typically do not.

Examples of sill in a Sentence

1. James Carroll:

   We spend most of our time and energy in a kind of horizontal thinking. We move along the surface of thingsbut there are times when we stop. We sit sill. We lose ourselves in a pile of leaves or its memory. We listen and breezes from a whole other world begin to whisper.

2. John Carter:

   It is outrageous that this administration would even consider using our military installations to shelter illegal immigrants who have crossed our southern border, president Obama needs to enforce our immigration laws and secure our border, not undermine our military at a time when our country is facing increased threats from radical Islamic terrorists. Last year, amid a surge of unaccompanied children streaming in from Central America, the Pentagon began housing thousands of unaccompanied illegal immigrant children at Joint Base San Antonio-Lackland, in Texas, Naval Base Ventura County, in California, and at Fort Sill, in Oklahoma. More than 10,000 unaccompanied minor children have streamed into United States over the Mexican border since October 1, the result of unchecked corruption and gang violence in their Central American homelands, and an effort by Mexican drug cartels to diversify into the very lucrative migrant smuggling business. The Department of Health and Human Service's Office of Refugee Relocation is required to take control of unaccompanied children once they enter the U.S., and the agency is once again being stretched to the limit by a surge that has reached an estimated 10,000 since October. In a statement, Fort Hood spokesman Tony Rheinlander said it is n’t even up to the Pentagon whether or not Fort Hood is used.

3. Pete Geren:

   Bob had read news reports of mold in the barracks at Fort Sill, Okla., bob said ‘Let’s get a plane and get out there. The soldiers and their families need to meet face-to-face with the secretary of the army.’.

4. Sigmund Freud:

   Innately, children seem to have little true realistic anxiety. They will run along the brink of water, climb on the window sill, play with sharp objects and with fire, in short, do everything that is bound to damage them and to worry those in charge of them, that is wholly the result of education; for they cannot be allowed to make the instructive experiences themselves.

5. James Carroll, O Magazine, October 2002:

   We spend most of our time and energy in a kind of horizontal thinking. We move along the surface of things…[but] there are times when we stop. We sit sill. We lose ourselves in a pile of leaves or its memory. We listen and breezes from a whole other world begin to whisper.
