Understanding the largest mineral group on Earth: the Silicates

Understanding Silicates

source: faculty.plattsburgh.edu

With the crust containing 46.6% and 27.7% oxygen and silicon, respectively, the silicates are (naturally) the most common group of minerals on the earth! Together with their abundance and their molecular properties, silicates also form the most structurally diverse group of minerals and reflect conditions of formation such as temperature, pH, volatile and silica content. Understanding the reasons for the diversity of silicates allows geologists to better understand geologic processes. This talk will provide an overview of the silicate groups (with models and pictures!) and how they are related to one another, as well as an extension to the broader geological context.

    • We meet in the Church Hall which is the building north of KnoxUnitedChurch.
    • To get to the Hall: When driving north on Midland just past Sheppard, you will pass the church which is on the corner. Then keep you eye out for a small laneway that runs south of the Hall. This leads to the parking lot behind (east) of the Hall.
      If you miss the laneway, keep going till you hit a small street on your right (east) called Rural Ave. Turn right (east) and look for a driveway into the Church Hall parking lot.
    • The door to the Hall is visible from the parking lot. The door is propped open for the meetings. Come in the door & walk up a half a flight of stair into the hall.

    Meetings are help on the First Wednesday of the month

    When: First Wednesday of each Month (except for July, August )

    • Although the meeting starts at 8 pm, try to get there earlier – the before meeting time is often just as much fun as the meeting.  Come as early as 7:30 pm because there is always something going on.
    • Before the meeting you can:
      • chat with other members & guest speakers
      • look at the Silent Auction Items displayed by members
      • see the special guest speaker displays
      • borrow a club library book from the cabinet
      • sign up for workshops, classes or other volunteer opportunities at the side table
