After a whirlwind fortnight of fieldwork in north-east Romania see my previous blog I started looking at the rocks we collected in much greater detail than the naked eye allows. What makes it interesting to economic geologists is a series of carbonate veins, m wide, enriched in REE.
This behavior is noted all over the world. Magic in the Air Her film not only illuminates hummingbird behavior — impossible to see at regular speed — but shows other unique angles on these tiny birds, such as how they appear from a lens planted deep inside a flower.
The tilting meant that on fieldwork, we had a fantastic transect across the range of crystallised rocks: Image via Mary Coolidge. This gives them a wide field of view — an advantage for detecting predators. We wanted to establish if these veins were crystallised from the same fluid that altered the roof zone of the complex.
The bird sees his own reflection as an intruder, so he attacks.
There are also occurrences of niobium and molybdenum within the intrusion. Through a combination of microscopy and geochemistry, my project aimed to provide an overview of rare earth element REE mineralisation from both a magmatic and hydrothermal perspective.
To do this we looked at the chemistry of a particular mineral: The south east of the area was really interesting: Also, what we recognize as just a reflection in a window might look like another bird to a bird.
To help prevent window strikes during migration, make sure your exterior light fixtures are well-shielded and are not producing dazzling glare. Click here to watch a high-resolution clip featuring special imagery and describing how she made the film, or click on the video below.
Why do birds slam into windows, and what can you do to prevent it? Watching hummingbirds in slow motion has turned up new insights into their behavior. You might notice that most of the bird-window crashes happen in spring.
The name merely surmises the difficulties chemists first had in separating the elements from each other, and this still presents challenges for the minerals extractive industry today. From fieldwork observations we began to see that the intrusion had been emplaced in a broadly horizontal magma chamber, which had subsequently been tilted towards the east during a large-scale mountain building event the Variscan orogeny.
The source could be a later carbonatite emplaced below the complex, but this hypothesis needs to be further explored. Below is a little summary of our main findings from the open access!
Most birds that are active during the day have eyes on either side of their heads. Evidence of their robustness is apparent in the film.
Thus, there is a lot of bird movement that would increase the likelihood of window strikes.Sponges are a special kind of marine animal that look like a plant.
They appeared on world oceans before million years ago. There are different species of sponges in the world. They live in colonies in different depth of the oceans.
Sponges don’t have any internal organs, arms or head. Bird wings are not the only part of their bodies designed for flight. Just about every part of a bird body is specially adapted to help the bird fly. A bird's center of gravity is the balance point between its two wings and between its head and tail.
If it were possible to perfectly support a bird right at its center of gravity without it squirming around, the bird wouldn't. Also, birds perceive colors differently from mammals. It’s likely that birds can see colors and intensities beyond what people can see.
To a bird’s eyes, the reflection in the window may be bright enough to look like a real bird. You might notice that most of the bird-window crashes happen in spring.
To learn more about Earth's innards, scientists have looked outward. Researchers like Maria Zuber, a geophysics professor at MIT, and Ishii have used evidence from space to support their conclusions about Earth.
Iron meteorites collected after their fall to Earth are pretty solid clues that the element is plentiful in the Universe. One such, lesser known, European rare earth element deposit is where my project was focused: the igneous Ditrău Complex in Romania.
It is an intrusion of magma within the earth’s crust (ca. 19 km diameter), which solidified over million years ago. Video shows how hummingbirds sing with their tail feathers.
