#Thread How a weak EIA affects the fragile #Himalayan ecosystem? Missing from mainstream discussions, #mountains need a strong EIA policy. Sharing our first case study (with @ReDraftEIA2020) on rampant limestone and chromite mining in Mizoram.

Over a period of last 3-5 yrs, the hill state of #Manipur has witnessed a steep increase in state-sponsored #mining activities for #limestone and #chromite. The state has been assessed to be holding large reserves of these minerals. #DraftEIA2020 #HimalayanWatch
Further, the NDA govt's Act East policy has given a huge thrust to industrial activities in the entire NE region. In Manipur, several private and government players are now operating for mining of limestone and chromite minerals. The issue is, most of them are flouting EIA norms!
Re-watching some shows while #socialdistancing for #MarchBreak? We're chatting this week about some of our favourites that have great #geology or interesting stories behind their #filminglocations.

#GameofThrones used #Iceland's #Thingvellir Park as the #BloodyGate. Its landscape is caused by the Eurasian and #NorthAmerican tectonic plates meeting there and pulling apart at a rate of 2 cms per year. This made a rift valley: low land between 2 separating continents.

#MagheramorneQuarry, #NorthernIreland, is the set for #CastleBlack and #TheWall in #GameofThrones. The quarry wall is used as a backdrop and effects make it look huge.
The site's limestone was used to make cement. #NS has a limestone quarry and cement plant in Brookfield.

Despite 2000 years of stone construction, #London has no indigenous building stone. Its geology is sand, gravel and clay. Stone has been imported since #Roman times along the #RiverThames to build that amazing city.

To build #Londinium (starting in 47 AD), Romans imported stone from many places in #England and from as far away as #Egypt, #Greece and #Italy. Part of the Roman defensive wall is still visible and many buildings have been uncovered (amphitheatre, forum, bath houses, etc)

Medieval #London had narrow streets and timber-framed, thatch houses so the #GreatFireofLondon destroyed much of it in 1666. Legislation afterward required stone or brick construction to prevent future fires. #Halifax NS passed a similar bylaw in 1857 after several fires.

Excited to see the #DowntonAbbeyMovie? Here's the history of that amazing building...which is actually #HighclereCastle in #England but we will call it by the name we all know and love: #DowntonAbbey!

@DowntonAbbey #DowntonAbbey's land was granted to the Church in 749 and held by it for 800 years. A bishop's home (a palace, really) was built in the 1300s. The land was taken from the church in 1551 during the #ProtestantReformation and it’s been owned by several families since.

@DowntonAbbey The bishop’s palace at the site of #DowntonAbbey was rebuilt in 1679 as a #brick manor house (the drawing below). Some of the brick can still be seen at the building’s rear. In the 1700s, formal gardens and paths were built.

We love TV show #TheCurseOfOakIsland which is about one of #NovaScotia's greatest mysteries! Here is a #geological take on the treasure hunt that highlights the searchers' challenge in figuring out what really happened on #OakIsland.

Like many islands in #MahoneBay, #NovaScotia, #OakIsland is a #drumlin - rock, sand, gravel and clay deposited by glaciers as the last ice age ended
about 12,000 years ago. Actually, the island is 4 connected drumlins.

Because #OakIsland is #drumlins, it may have layers of #gravel below sea
level which could explain the flood tunnel mystery. Searcher shafts might
just be intersecting sea water naturally flowing underground through porous gravel.
