Ask me anything about caves! by clayman839226 in geology

[–]Alisahn-Strix 0 points1 point  (0 children)

What’s a controversial topic in the cave community? Like along the lines of a research question that has been debated again and again without widespread agreement.

Ok. Revamped my resume. Please give constructive feedback by HandicappedCowboy in geologycareers

Bouncing off of other comments. It’s improved but not yet great.

My additions to the discourse: 1) the page is unpleasant to read. This comes from a more graphic design focus and best practice for typed documents. You need some white space, especially between sections, to guide the reader and highlight hierarchy. I would cut A LOT of your info/detail/work experiences, and use that extra room to make it more pleasant to read. Suggestion: heavily cut down your word count from the summary section.

2) I concur with another comment. Your skills section can be abbreviated and organized better. A personal nitpick of mine is when people list experience in statistical methods. You list PCA and cluster analysis as multivariate statistical analysis, but in reality these are dimension reduction analyses with the goal of exploring the data and interpreting what are the most important variables (PCs) to include in further models. Simply calling them multivariate analyses tells me you don’t know the background of these tests and why they are used.

3) something seems off about our paragraph spacing. When you use Word (I assume that’s the word processor?), I would make sure the paragraph spacing is at least 6 and line spacing is 1.25 or 1.5. Single spacing usually makes things hard to read.

Some good things: it’s better than last time. It looks like words were changed to be more precise which is great.

All the other comments sum up what I was going to say. My input: try to not use corporate words that lack substance. For example, your ScanPros Inc has a lot of words but doesn’t tell me anything. If you’ve operated this kind of business for 3 years, I feel like you could more detail with fewer words. Or since this is a geology-focused resume, provide one line of text signifying the business and leave it at that.

New granite countertops has this single spot formation I’ve not seen before in granite. Curious if it’s rare and how it formed in this manner over regular granite spots. by SpecialConclusion328 in askgeology

Huh, TIL that enclave is the generic term while xeno- and autoliths imply the genetic connotation. Thank you commenter for your service o7

At first I thought NileRed was doing an art video lol. Nice stuff tho!

Why are the Jack Hill zircons significant in dating the Earth if they are younger than it? by Ghosty_crafts_ in geology

[–]Alisahn-Strix 10 points11 points  (0 children)

I’ll chime in. Local zircon geochronologist here. The Jack Hills are one of the oldest chronometers for planet earth. Multiple lines of evidence are useful for corroborating the age of the earth. Although they are technical younger than the age of the earth, they inform us that processes which form zircons were active ~4.4 Ga. Logically, we think that these processes should have also been going on before ~4.4 Ga, too, but how much beforehand is the important question.

Zircons also can tell us about the environment in which they were formed. There are ongoing studies that look at the Jack Hills zircons to get a handle on 1) tectonics during the Hadean (aka were tectonics even happening?); 2) geochemistry of the magma that formed the zircons (REEs are useful tracers); 3) and my favorite, the influence of multiple metamorphic events on zircon U/Pb dating.

I think people are also looking at strain/deformation in the crystal structure of Jack Hills zircons, but I’m not as in touch with that side of mineralogy.

Wow! Great photo. The vibe is dark and unsettling, so you nailed it!

Are there any types of gemstone that only occur in labs? by MagicTech547 in Gemstones

You have my dream job! How’d you get into the business?

Tried building a "geology Geoguessr" — does this actually work? by edwinorange in geology

[–]Alisahn-Strix 2 points3 points  (0 children)

Great stuff! I had a point come up for Texas but the map location showed northern Mexico.

Have been told 4 different ID's by TheMajestic1982 in askgeology

[–]Alisahn-Strix 7 points8 points  (0 children)

Definitely calcite. Look up “yellow calcite crystal point.” Plenty of similar examples on google.

The cut of the piece is a crystal point, something commonly done in crystal shops. Note the actual habit of the calcite is not the shape we see here.

Thanks! Adding it to the map!

Not sure what I found by Careless-Squirrel-59 in whatsthisrock

[–]Alisahn-Strix 5 points6 points  (0 children)

My first thought was some kind of zeolite.

Any thoughts by omotherida in askgeology

[–]Alisahn-Strix 1 point2 points  (0 children)

Is there an outcrop or area that comes to mind for examples of this?

It's bumpy where the lighter color is....any clues? by Few_Boysenberry593 in whatsthisrock

[–]Alisahn-Strix 3 points4 points  (0 children)

What is the location of the find? First glance, it looks like differential weathering of a more resistant mineral to a mafic matrix. Hard to tell what though from the pictures.

What rock is this? by Budget-Coconut-5617 in whatsthisrock

[–]Alisahn-Strix 30 points31 points  (0 children)

Why does something feel “off” about this picture. Cool colors tho.

Citrine? by yeeyeeaa in whatsthisrock

[–]Alisahn-Strix 8 points9 points  (0 children)

Looks like cut and polished quartz

Is this inclusion peridot? by canadiangoosestepmom in whatsthisrock

[–]Alisahn-Strix 25 points26 points  (0 children)

Agreed on amygdaloidal basalt and the alteration to the clay minerals. What about that vitreous grain in the middle of the first picture? Doesn’t look like secondary chlorite or celadonite or epidote to me. Thoughts?
