Rocks containing diamonds are geological formations where natural diamonds, Earth's hardest known material, originate.

[camblorite]

Lamproite with crustal xenolith (the lighter zone), from Murfreesboro, Arkansas, USA.

Lamproite is a potassic to ultramafic, dark-colored igneous rock group.

Xenoliths are rock fragments carried by igneous rocks. They are older and from a different source than the igneous rocks that contain them.

The pedogenic carbonates, found mainly in arid and semi-arid regions of the world, are commonly referred to as calcretes or caliche or kankar. These are authigenic carbonate products which occur in association with soil, forming the residual regolith. Many rock types can produce calcretes upon weathering and denudation, but calcrete derived from certain rocks like kimberlite/lamproite acts as an exploration guide. Calcrete is a prominent sampling medium in diamond-rich countries like Australia and South Africa whereas it has not received popularity in the Indian context. Kimberlites being ultrapotassic in nature and owing to the enrichment of olivine and serpentine often produce calcrete duricrust as a capping. Recently more than twenty lamproites have been discovered in the Telangana state by the Geological Survey of India. These occurrences unravel a new panorama that the state has a substantial potential for occurrence of more kimberlite/lamproite clan rocks. An attempt has been made here to test the geochemical affinity of calcretes from various locations within Nalgonda district. The geochemical data of calcrete samples of this study has been compared with published geochemical data of lamproites of Ramadugu Field, to understand their geochemical association to kimberlite/lamproite. The calcretes are low in SiO2 (33.92-45.1 wt %), high in K2O (1.07-2.21 wt %) and CaO (0.78-13.61 wt %). When compared to other major elements, MgO displays low concentration. The trace elements are found to be enriched in some of the samples collected in close vicinity of known lamproite occurrences. The samples show high degree of chemical weathering, alteration and compositional variation indices. It is observed that enrichment of elements like Cr, Nb, Ba, Ti, Zr etc. indicates, similar to parent kimberlite/lamproite rock, favourable targets for further ground exploration in virgin areas. In the present study, two samples, towards five kilometers northeast of Vattikodu Lamproite Field, possess higher concentrations of Nb (>25ppm), Ba (>400 ppm), Zr (>650 ppm) and Ti (>3500 ppm) which stand out as plausible explorable targets for further ground investigations. Further investigations on these two locations are suggested to ascertain whether or not these two targets unveil new kimberlites/lamproite occurrences in the area.

Appreciation Post

Jesus christ, I still am lost for words to describe the beauty and humility of my friends. I don’t know if everyone in the world is as beautiful as they are, and our mission is to unlock that kindness, or if I just ran into the best bunch of people. Either way I am lucky as fuck to have them, and each one of them is so unique and beautiful I HAVE TO MAKE A POST.

Ciara, you been my best friend for years, the biggest support system I’ve ever had, saying exactly what I need to hear even when I can’t do the same for you. You know the dark side of the world and yet, god damn you look for the best. I am so proud of you; beautiful, smart, motivated and strong throughout it all. And jesus, you has every right to not be strong, but no - you look towards a positive future and are consistently beautiful and courageous everyday and I am so proud of you because of that.

Ali, I haven’t actually known you for very long, but since we started talking we’ve never, ever stopped. You have the best laugh and smile and I love when you do! You have been through so much, but never once have you doubted yourself or given up and for that, you are more mature and strong than I ever imagined someone could be. You’ve had to mature quickly, but oh you always stayed true to yourself, and bluntly, brutally honest and that is one of my favorite qualities about you - keep it, because it’s outstanding. (a-beautiful-little-fools-world.tumblr.com/)

Reo, I have known you very very little time in fact, and the reasons for us getting close are a bit hilarious, but I am so, so glad it happened. You only just became an adult and look at you - working fulltime, looking at moving out, starting a real, independant life! That is so frightening and crazy and if it were anyone else I would be worried but not with you. I have so much faith in you to do well, to be yourself, to make friends and to move on. You have fought so hard babe and you deserve to get it all repaid. (pre-serumstevie.tumblr.com)

Prabby, you are honestly family. You are my undeniably my sister and you always know how to make me smile. You are the most positive and upbeat person I know, and you are there for me through everything - you’re the laugh I needed to hear, the words I couldn’t get out, the ideas that I have never considered. I honestly don’t know where I would be without you and while we are both complete opposites and the almost the exact same, you are the world to me and I hope you get the world in return. (hakunamatatasexygoldfish.tumblr.com/)

Toni, you are my actual sister ;) We’ve had a rough few years (hormones suck) but I never considered you more my friend than I have now. You really supported me when I needed you, and I really cherish our time together. I really love that you’re starting to find more confidence and interest in languages, and I’m glad I can be there to guide you through it. You were always a real inspiration to me, and I am proud to have you in my life. I love you and I hope we can grow alongside each other now. (honepski.tumblr.com/)

These are just some of the amazing people in my life - the ones with active tumblrs - and I don’t even know where I would be without them. Every single one of them literally makes my day every single day and I couldn’t express my gratitude for having them in my life. :’)

Plans for Day 12: Crater of Diamonds State Park, AR

Plans for Day 12: Crater of Diamonds State Park, AR

Projected date: May 31, 2015.

Crater of Diamonds State Park, the only diamond-producing site in the world open to the public, stands out as a unique geological “gem” for you to explore and enjoy.  Here you can experience a one-of-a-kind adventure hunting for real diamonds. You’ll search over a 37 1/2-acre plowed field, the eroded surface of an ancient volcanic crater that 100 million years ago…
