    Rocks
In summary, the conversation is about someone asking for help in identifying some rocks they collected at Lake Luzerne. The pictures provided were too blurry, but someone suggested that they could possibly be granite. The original poster added a clearer picture and another person identified it as a Quartz Monzonite.

Could someone identify these rocks I collected at Lake Luzerne yesterday?

A bit too blurry for me, but perhaps that's just my eyes.

Could be granite, but the pics are way too blurry to tell.

Yeah, it's a bit blurry because I took the picture off of my webcam so I apologize for the picture quality.

It's particularly the second picture I think looks a bit like granite, but I can't really tell. If it is, I'd think it would look like this: http://www.lewis-clark.org/media/NewImages/VIEWS/geol_granite-gray-hyndman.jpg

I got an overhead shot of it and reduced the brightness. I hope this helps.

I added the picture onto the original website I posted. It's the third picture down.

Let me know if you have any problems accessing it.

Since the books in the background are in focus and the rock isn't maybe if you take a step back, you can get a sharp picture of the rock. Just a thought.

Looks like a possible Quartz Monzonite to me. Seems to be a fair bit of k-feldspar and lacking in Qtz. That could just be the lighting in the photo however.

1. How do you identify rocks from Lake Luzerne?

To identify rocks from Lake Luzerne, you can start by examining their physical characteristics such as color, texture, and shape. You can also use a hand lens to look for any distinctive features or patterns on the rock's surface. It is also helpful to compare the rocks to known rock types found in the area.

2. What types of rocks can be found in Lake Luzerne?

The most common types of rocks found in Lake Luzerne are sedimentary rocks, such as sandstone and shale, which were formed from layers of sediment. Igneous rocks, like granite and basalt, can also be found as they were formed from molten magma. Metamorphic rocks, such as slate and marble, can also be found as they were formed from existing rocks that were subjected to heat and pressure.

3. Are there any rare or unique rocks in Lake Luzerne?

Yes, there are some rare and unique rocks that can be found in Lake Luzerne. These include fossils, which are the remains of ancient plants and animals preserved in sedimentary rocks. You may also find geodes, which are hollow rocks filled with crystals, and glacial erratics, which are large boulders that were transported and deposited by glaciers.

4. How old are the rocks in Lake Luzerne?

The rocks in Lake Luzerne range in age from hundreds of millions to billions of years old. The oldest rocks are usually found at the bottom of the lake, while the youngest rocks are found towards the top. This is because new layers of sediment are constantly being deposited on top of older rocks, creating layers that can be used to determine their relative ages.

5. How can identifying rocks from Lake Luzerne be helpful?

Identifying rocks from Lake Luzerne can be helpful in understanding the geological history of the area. It can also provide insights into the types of rocks and minerals that are present, which can be useful for industries such as construction and mining. Additionally, identifying rocks can also be a fun and educational activity for people interested in geology and the natural world.
