This document describes several landforms produced by wave erosion along coastlines:
- Headlands jut out into the sea at the end of cliffs. Bays form sheltered inlets in weaker coastal rocks between headlands.
- Arches form when waves erode caves completely through headlands. Stacks are isolated pillars that remain when arches collapse.
- Other landforms include caves undercut at the base of cliffs, wave-cut platforms of gently sloping land left after cliff retreat, and blowholes which form when joints in cliff rocks connect eroded caves to the surface.
Minerals are formed by changes in chemical energy in systems which contain one fluid or vapor phase. In nature, minerals are formed by crystallisation or precipitation from concentrated solutions. These solutions are called as ore-bearing fluids. Ore-bearing fluids are characterised by high concentration of certain metallic or other elements.
Fluids are the most effective agents for the transport of material in the mantle and the Earth's crust.
CLASSIFICATION OF ORE DEPOSITS
The Mixture of ore minerals are gangue minerals form an Ore deposit. The ore
deposits are generally found enclosed within the country rocks. The ore deposits
are formed in many different ways. Depending upon the process that may
operate to produce them, the ore deposits may be classified as follow:
Magmatic ore deposits.
Sublimation ore deposits.
Pegmatitic ore deposits.
Contact metasomatic ore deposits.
Hydrothermal ore deposits
Cavity filling deposits.
Replacement deposits.
Sedimentation ore deposits.
Evaporation ore deposits.
Residual and mechanical concentration deposits
Metamorphic ore deposits.
MAGMATIC ORE DEPOSITS:
The magmatic ore deposits are the magmatic products which crystallize from
magmas. The magmatic ore deposits are classified as follows:
o Early magmatic deposits
o Late magmatic deposits
Early magmatic deposits:
Early magmatic deposits are formed during the
early stage of the magmatic period. In this case the
ore minerals crystallize earlier than the rock
silicates. The Minerals of Nickel, Chromium, and
Platinum are usually found as early magmatic
deposits. The early magmatic deposits can be sub
divided into two groups:
o Dissemination deposits
o Segregation deposits
Dissemination deposits:
When magma crystallizes
conditions, a granular igneous rock is formed. In
such a rock early formed crystals of
may occur in dissemination.
Segregation deposits:
Magmatic segregation deposits are
formed as a result of gravitative
crystallization differentiation. In
case, the ore mineral which crystallize
early, get ocean-trated on a particular
part of igneous part. The ore deposits
thus formed are known as “Segregation
deposits”.

Late Magmatic Deposits:
The ore deposits which are formed to
called late magmatic deposits. The late magmatic deposits contain those ore
minerals which have crystallized at rather low temperature from the residual
magma. The magma which is left after crystallization of early for
is called residual magma. This magma frequently contains many ore minerals. The
late magmatic deposits include most of the magmatic deposits of iron and
titanium ores, these deposits are almost always associated with mafic igneous
rocks.
SUBLIMATION DEPOSITS:
Sublimation is a very minor process of formation of ore deposits. Sublimation
deposits contain only those minerals which have been volatilized by hear and
subsequently redeposit in the same form at low temperature and pressure. The
sublimation deposits are found associated with Volcanoes and Fumaroles. Sulfur
of this origin has been mined in Japan, Italy, and Mexico.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Formation of headlands and bays.ppt
1. Stack
• A pillar for rock
which has been
isolated from the
cliff due to the
erosive nature of
the waves.
LANDFORMS PRODUCED BY WAVE EROSION
2. LANDFORMS PRODUCED BY WAVE
EROSION
Headland
• This is a part of
the coastline that
juts out into the
sea and usually
ends in a cliff.
Bay
• A wide curved inlet
of a sea.
3. Arch
• An opening through
a rock.
Cave
• A deep hollow
produced by the
action of the waves
usually at the foot
of a cliff.
LANDFORMS PRODUCED BY WAVE EROSION
4. LANDFORMS PRODUCED BY WAVE EROSION
Wave cut notch
• The foot of the
cliff which is
undercut.
Wave cut platform
• This is the gently
sloping land left on
the foot of a
retreating cliff.
5. Formation of headlands and bays
Sea attacking a coastline
of varying resistance will
erode the weaker rock
more quickly
The result is that a series
of headlands form on the
harder rocks………
…..and sheltered bays
form in the weaker rocks
6. HEADLANDS, BAYS AND BEACHES
1. a. Waves attack both sides of a
headland, producing caves;
2. b. Sometimes these are eroded right
through the headland to form arches.
3. c. When the roof of the arch collapses
it leaves a pillar or stack;
4. d. When the stack collapses it leaves a
stump.
10. BLOW HOLES
• Caves develop well in jointed rocks as
bedding planes are open by abrasion
and hydraulic action. If a joint runs
from the cave to the cliff top the
hydraulic action can eventually force
this joint open like a chimney inside
the cliff .
