Meeting Time: 7:30 pm
Speaker: Brian Curtis
Topic: Crystal Structures and Shapes
Location: In-person and via Zoom Link on the GMS Calendar here
The March meeting stepped away from geology for a moment and presented several ways to work up a GMS or personal business card. Having one available can be a big plus when representing the club at public outings; having a way to direct people to our website in an accurate and professional manner.
The April meeting will try something different. Club member and frequent attendee Brian Curtis will present on Crystal Structures and Shapes. This is an important skill to learn if trying to identify minerals in the field. Often, a choice between two possible minerals can be made based on the form of any crystals present, even if the color and hardness of the minerals is similar. Brian’s presentation describes the crystal classes with examples and goes on to explain why natural factors can influence the shapes that you actually see.
The meeting link will be sent out early in the month.
