  2. Fulgurite - Wikipedia

    en.wikipedia.org/wiki/Fulgurite

    Material properties (size, color, texture) of fulgurites vary widely, depending on the size of the lightning bolt and the composition and moisture content of the surface struck by lightning. Most natural fulgurites fall on a spectrum from white to black. Iron is a common impurity that can result in a deep brownish-green coloration.

    The approximate age of the fulgurite was determined using thermoluminescence (TL). [20] Quartz sands can be used to measure the amount of radiation exposure, so if the temperature at which the fulgurite was formed is known, one could determine the relative age of the mineral by examining the doses of radiation involved in the process. [3] [20]

    A fulgurite from the Mauritanian desert Trinitite, in common with several similar naturally occurring minerals, is a melt glass . [ 46 ] While trinitite and materials of similar formation processes such as lavinite are anthropogenic, fulgurites , found in many thunderstorm -prone regions and in deserts , are naturally-formed, glassy materials ...

    There was also a hypothesis about the fulgurite origin of australites, as a result of a lightning strike into sand or sandy rocks. [5] A new hypothesis about the origin of australites arose in the late 1960s based on data received from the American Surveyor 7 spacecraft, which landed in 1968 near the Tycho crater.

    Mineralogy is a subject of geology specializing in the scientific study of the chemistry, crystal structure, and physical (including optical) properties of minerals and mineralized artifacts. Specific studies within mineralogy include the processes of mineral origin and formation, classification of minerals, their geographical distribution, as ...

  7. Piller is the manager of dozens of companies that own more than 50 properties in Brooklyn, Manhattan and the Bronx, according to a HuffPost/WNYC review of HPD registration data and property records. In the past decade alone, at least 10 families have sued Piller, or one of his companies, claiming that he failed to clean up decaying lead paint ...

  8. Lechatelierite - Wikipedia

    en.wikipedia.org/wiki/Lechatelierite

    The result is an irregular, branching, often foamy hollow tube of silica glass called a fulgurite. [2] Not all fulgurites are lechatelierite; the original sand must be nearly pure silica. Lechatelierite also forms as the result of high pressure shock metamorphism during meteorite impact cratering and is a common component of a type of glassy ...

    Methadone clinics have since become the targets of NIMBYs and politicians who view them as nothing more than nuisance properties. In the late ’90s, then-New York City Mayor Rudy Giuliani tried unsuccessfully to cut methadone programs serving 2,000 addicts on the grounds that despite the medication’s success as a treatment, it was an immoral ...
