War Memorial #2394 ~ Carmarthen - RWF EarthCache

This is an EarthCache. There is no geocache hidden at or near the War Memorial. To log a Find on this EarthCache you need to read the short geology lesson below, examine the rocks forming the Royal Welsh Fusiliers War Memorial, and then send me answers to the questions that follow. You can send answers using the Message function of the Geocaching app, or using the email address in my Profile. You can log a Find as soon as you have sent answers, and I will reply with clarifications if any answers are wrong.

Lesson: limestone and marble

Limestone is a Sedimentary rock formed from the shells and other remains of ancient sea creatures, laid down millions of years ago. It is rich in Calcium Carbonate and has a high pH. Limestone disolves in acids, and this can cause it to erode because of Acid Rain. Some related rocks, named Dolomite, have Calcium Magnesium Carbonate. Most Limestone and Dolomite rocks in Britain have very fine grains, scarcely visible to the naked eye, although Oolitic Limestones are composed of small spheres of Calcium Carbonate up to 2mm in diameter. Most Limestones are light grey to mid grey in colour. Because Limestones are formed from ancient sea creatures they often contain fossils, especially shell fragments.

Marble is a Metamorphic rock, formed when ancient Limestone or Dolomite is chemically altered by high temperature and/or pressure. Marble has a crystalline structure without visible grains. Although some Marble is pure white, most shows some discolouration because of other chemicals in the Limestone that it derived from. Grey veins in Marble are caused by Iron compounds, as are red or pink colours, whilst green Marble contains Serpentine (a Magneium-Iron-Sulphide). The most famous Marbles in the world come from Carara in northern Tuscany, Italy. They date from the Jurassic Period, and many have abundant grey veins in their white, crystalline rock.

Questions

Examine the east side of the War Memorial, which commemmorates the Crimean War and is surrounded by a remarkable metal fence composed of crossed muskets with bayonets.

1: describe the rock that forms the majority of the monument, focusing especially below the word CRIMEA. Is the rock layered or uniform, what colour is it, and does it hold any fossils? 

2: focusing on the 'flowers' sculpted around the plaque, below the word CRIMEA, describe whether the memorial has suffered from erosion since it was erected in 1858. Are the 'flowers' sharp-edged or rounded? 

3: describe the rock that forms the plaque commemmorating the Royal Welsh Fusiliers, below the word CRIMEA. Is the rock layered, uniform or veined, are the veins aligned in one direction or irregular, and are the veins of equal width or are they wider in certain areas of the plaque? 

4: what colour are the veins on the plaque, and what chemical is likely to be the cause of this colour? 

5: is the monument made of Sedimentary rock or Metamorphic rock, and is the plaque made of Sedimentary rock or Metamorphic rock? 

Although not necessary from an EarthCache standpoint, please tell me the name of the maker of the monument and where he worked (carved in small letters at the bottom of the east side of the monument), just to show that you aren't getting your answers off the internet.
