Can someone please describe me Israel's geology in the context of plate tectonic. Explain how it had formed. If it is a convergent boundary or divergent boundary, which plates have been involved and how?

TIA

Mediterranean Plates
Phat:

I hope this helps, or at least gives you somewhere to start:

Meanwhile, I will try to find you one that zooms in a little closer on the Horn of Africa, Arabia, and the Levant.

I think that I remember that the Dead Sea/Jordan Valley is an extension of some sort of the East African Rift. Whether the Israeli part is pulling apart like Africa, I don't remember at all. I'll try to find something, too.

Red Sea rifting
It looks like the red sea is closing and so Israel will be in a mountain building zone.

East AFrican Rift Valley

The Middle East is part of a larger geological zone called the East Africa Rift Valley, where plates are pulling apart.

Edited to supply a better link.

Does the following sum it all up or am I missing something?

Explanation of Formation:
The origin of the Dead Sea Rift, which is the plate which Israel is located on, has been described as a rift defined by 2 sets of normal faults, and there are 2 theories explaining the origin of the Dead Sea.

1. The Graben Theory (Vertical Movement)
The Dead Sea is a graben formed by vertical movement along parallel faults extending N-s and along flexture; each fault caused a small down thrown to the center of the graben forming step faulting. As a result of this movement the central part of the graben was lowered relative to its shoulders forming the Dead Sea, the Jordan valley and Wadi Araba.

2. The Horizontal Movement Theory
The Dead Sea Rift was formed mainly as a result of horizontal displacement a long normal faults. In which 2 faults with horizontal left lateral displacement, overlapped in the present Dead Sea area. The northword horizontal movement of the Arabian plate relative to the Sinai plate resulted in a rhombus shaped structures in the area of overlap between the two faults forming the Dead Sea.

Type of Boundary:
The Middle East is part of a larger geological zone called the East Africa Rift Valley, where plates are pulling apart, and thus it is a divergent boundary.

What plates were involved and how:
The plates that have been involved would be the Dead Sea Rift and the Arabian plate. Also these plates were involved due to the fact that the Dead Sea Transform is a plate boundary separating the Arabian plate from the African plate and connects the divergent plate boundary in the Red Sea to the convergent plate boundary in the Red Sea to the convergent plate boundary in the Taurus mountains in southern Turkey.

Thanks in Advance!

Depends on your source
Since you copied that from an online source you should give credit to that source.

It appears to be from professional geologists and only those of us who are also expert in the area could make any further comment.

Re: Depends on your source
Actually, I don't think Phat copied that, Nosy, but they should still cite their source(s).

--------
edited to add:

I take that back. You are right Nosy. Part of it is copied - points 1 and 2. The English and technical terms were rather poorly presented, so I thought Phat wrote it out. Turns out it's probably a translation problem and the person who did the original translation from Arabic (Jordanian?) to English did not do a good job.

Re: Depends on your source
All sources used will be given credit, I'm not worried about that. I just want to know if I got the answers to my question right, because if it's wrong then I'm not going to use that source, thus no credit will be given. That's why I'm asking you guys to look over it and tell me if I missed something or if something is wrong.

Here are some comments. Hope they help.

quote:
Explanation of Formation:
The origin of the Dead Sea Rift, which is the plate which Israel is located on, has been described as a rift defined by 2 sets of normal faults, and there are 2 theories explaining the origin of the Dead Sea.

In this portion, I would write about the characteristics of the Dead Sea and adjacent area, such as it's elevation, local geology (underlying rocks and local faults), what makes it special, and the plates that occur in that area. (Note: the "Dead Sea Rift" is not a plate.) Keep the short intro to the theories for formation (the last sentence), if they hold up to additional research.

Points 1 and 2: Discard completely and start over from another source. Your source is too poorly written/translated to be of any use. Note their theories, but use another source with better explanations.

quote:
Type of Boundary:
The Middle East is part of a larger geological zone called the East Africa Rift Valley, where plates are pulling apart, and thus it is a divergent boundary.

Is this paper only about the East African Rift or about the boundary where the Dead Sea occurs? Because if it's on the Dead Sea, then you need to include a description on that type of boundary here.

quote:
What plates were involved and how:
The plates that have been involved would be the Dead Sea Rift and the Arabian plate. Also these plates were involved due to the fact that the Dead Sea Transform is a plate boundary separating the Arabian plate from the African plate and connects the divergent plate boundary in the Red Sea to the convergent plate boundary in the Red Sea to the convergent plate boundary in the Taurus mountains in southern Turkey.

Again, the Dead Sea Rift is not a plate, although in the following sentences, you do mention the other one. This paragraph is a mess and needs to be completely re-written. Go HERE for a good description of plate boundaries and how they word.

If I were you, I would do a bit more research and remember not to copy someone else's work word for word... unless you put it in quotations and cite it. You should also read up a bit on plate boundaries so that you can understand them better.

The thing is that I'm suppose to explain how Israel's geology in the context of plate tectonic formed, not the Dead Sea Rift, but I can't find anything about it and non of the links posted here really nail that question on the head.

This paper is about Israel's geology in the context of plate tectonic, not about the Dead Sea, and the question was which plates have been involved and how...

Can someone give me a straight forward explanation of how Israel's geology in the context of plate tectonic formed, and which plates have been involved?

TIA

The links you already have seem to indicate that Israel is on the eastern edge of the African Plate where it is rifting from the Arabian Plate. There may not be too much more detail online, but searching some combination of rift, plate, jordan, tectonic, and such on Google or Scirus might get what you're looking for. I can tell you a little about the Delaware Basin, but the Near East is out of my field.

Thank you Coragyps!

Now how did the African, and the Arabian plate form? I'm more interested in the African plate since Israel is on it.
