Who's Fault Is It?

In our final year of B.Sc., we had been to Bhuj in the state of Gujarat for our annual field trip. We were supposed to be heading for Malvan in the southern part of Maharashtra. But some crazy circumstances forced us to head north into the dry region (most of us know what I mean by dry region :p) of Kutch. It was unexplored and uncharted territory. Our professors were relying on past experiences and reference materials. It very often happened that we would stumble upon something completely new and start breaking our heads over the mystery of the outcrop. It was during one of these exploratory trips that our professor realized that there was something weird across the road that ran in front of our lodging.

So, one fine morning (half asleep actually), we walked up this small hillock. Once we were at the top, our professor pointed out this feature to us.

Naturally, we were confused. We did notice that long linear mark on the surface. But we had no idea what it could possible be. Lots of options ran through our minds. A dike maybe? Or was it a fault? It could also be some thin rock strata of a different composition. With these thoughts, we started our investigation.

We began with the thin zone marked in red in the pic above. The material within that was definitely fine grained. Extremely fine, to the point that it felt like it was crushed. It was highly jointed, with sets of joints running perpendicular to the length of the zone as well parallel to it. As expected, there was intense venation around it.

We cast our attention to the surrounding area. We noticed a reddish ferruginous sandstone bed on one side. But,no matter where we searched we couldn't find the corresponding outcrop on the other side. This eliminated a lot of our guesses and we had narrowed it down to one option. It was definitely a fault. But we needed proof. And that we got.

Small striations (or as we know them: slickensides) were noticed by someone on the rocks on the supposedly upthrown block. And as a bonus, we got some minor faults at the top of the hill. So, that was it then. Mystery solved.

It was our fault. :P

P.S. The road is called the Bhuj Airport Road and the fault is located right opposite to Navchetna Lodge. So, if you ever feel like, you can surely go. Maybe you'll find a pencil or something which one of us left behind.

Getting Started...

Almost a week back, I started the next two years of my academic life (it is getting boring now!) in IIT Bombay. It took a crazy amount of hard work and mind numbing hours with books I would rather not start naming here. But I made it. I was looking forward to making new friends, getting to know people from different places and backgrounds. Know their story. Try to figure out if I had anything in common with the twenty nine other faces in that classroom. But I did not realize that it would be this hard.

I know it is too early to draw out conclusions and call this a doomed cause. But maybe something could be done to make this transition easier. Something that will make budding geologists recognize the talents of their peers spread all across the country. Why, just the other day, I came to know that there are approximately 500 departments dealing specifically in Earth Sciences. (Whoa!)

Now that is a number that is both amazing and surprising in equal amounts. Amazing because I never knew these many institutions catering to this field even existed in India. And surprising that I hadn't heard about them before. Where are the students of these places? More than that, how are they? Are they brilliant geologists? Expert field or lab researchers? Do they have the same interest as all the students I have encountered till now? Or are they different? If so, how? So many questions...

I am beginning to understand some of the answers to these questions as I sit and look around in my current class in IIT. I see people with the same exact doubts that go through my mind. People making the same sad geology jokes that are starting to get old. (I don't think that's gneiss, we must do something about this schist) I see the same excitement when talk of field work crops up. Maybe we are not so diverse after all. Of course, we all have our own unique capabilites, unique quirks and point of views. But the basic fabric (ah! a geology term finally!) that makes us geologists remains the same.

So, here I am. I think what we, the students of geology, need is a platform. A place to share our experience. Let others know about ourselves. Let out our thoughts and peek into the mind of like-minded individuals. Learn, teach, understand, grow...

P.S.

It will be a momentous task I know. It is not going to easy to get going. But I am sure that with your support, this will seem as easy learning the names in Indian Stratigraphy of the three types of rocks.
