The geological sequence of events appears to have been the following: - After the deposition of the Eocene (or Oligocene) limestone - which reposes upon a floor of basalts and trachytes - basalts and basic tuffs were ejected, over which, during a period of very slow depression, orbitoidal limestones of Miocene age - which seem to make up the great mass of the island - were deposited; then elapsed a long period of rest, during which the atoll condition existed and the guano deposit was formed; from then down to the present time there has succeeded a series of sea-level subsidences, resulting in the formation of the terraces and the accummulation of the detritus now seen on the first inland cliff, the old submarine slope of the island.
After this treatment the upper 2 or 3 in, of soil are well pulverized, and fertilizers added, usually, to prevent reintroduction of seeds of weeds, in the form of guano or chemical manures.

In 1848 the two London loans and accumulated interest were covered by a new loan of £3,736,400, and the home debt was partially liquidated, the sale of guano giving the treasury ample resources.
Lavish expenditure followed and the government was soon anticipating its revenues by obtaining advances from guano consignees, usually on unfavourable terms, and then floating loans.
In 1876 interest payments on account of this debt were suspended and in1879-1882the war with Chile deprived Peru of her principal sources of income - the guano deposits and the Tarapaca nitrates.
In 1889 the total foreign debt, including arrears of interest, was £54,000,000, and in the following year a contract was signed with the Peruvian Corporation, a company in which the bondholders became shareholders, for the transfer to it for 66 years of the state railways,, the free use of certain ports, the right of navigation on Lake Titicaca, the exploitation of the remaining guano deposits up to 3,000,000 tons, and thirty-three annual subsidies of £80,000 each, in consideration of the cancellation of the debt.
A large increase in imports, caused by fictitious prosperity and inability to obtain drafts against guano shipments, led to the exportation of coin to meet commercial obligations, and this soon reduced the currency circulation to a paper basis.
With the vast sum raised front guano and nitrate deposits President Balta commenced the execution of public works, principally railroads on a gigantic scale.
The true object of Chile was the conquest of the rich Peruvian province of Tarapaca, the appropriation of its valuable guano and nitrate deposits, and the spoliation of the rest of the Peruvian coast.

It is found in the form of its acid potassium salt in many plants, especially in wood-sorrel (Oxalis acetosella) and in varieties of Rumex; as ammonium salt in guano; as calcium salt in rhubarb root, in various lichens and in plant cells; as sodium salt in species of Salicornia and as free acid in varieties of Boletus.
The soluble phosphates washed out of the guano may become fixed by entering into combination with the elements of the rock beneath.
Of guano will add to the productiveness of the crop. On good soil and in favourable seasons the yield sometimes reaches to 40 bushels per acre.

At the time of Roggeveen's discovery the island probably contained from 2000 to 3000 inhabitants of Polynesian race, who, according to their own tradition, came from Rapa Iti (Little Rapa) or Oparo, one of the Tubuai or Austral group. In 1863 a large proportion of the inhabitants were kidnapped by the Peruvians and transported to work at the guano diggings on the Chincha Islands.
Birds flock to them in great numbers; in consequence they are completely covered with guano, which gives them a snow-white appearance.
The soil is suitable for the cultivation of almost all kinds of tropical produce, and it is to be regretted that the prosperity of the colony depends almost entirely on one article of production, for the consequences are serious when there is a failure, more or less, of the sugar crop. Guano is extensively imported as a manure, and by its use the natural fertility of the soil has been increased to a wonderful extent.
Gutta, rubber, rattans, mangrove-bark, edible nuts, guano, edible birds'-nests, &c., are all valuable articles of export.

Among the non-metallic minerals are nitrate of soda, borate of lime, coal, salt and sulphur, together with various products derived from these minerals, such as iodine, sulphuric acid, &c.

In 1862 a treaty of peace and commerce with the United States was ratified, and in the following year a similar treaty was concluded with Belgium; but new causes of disagreement with Chile had arisen in the discovery of rich beds of guano on the eastern coast-land of the desert of Atacama, which threatened warfare, and were only set at rest by the treaty of August 1866, in which the 24th parallel of latitude was adopted as the boundary between the two republics.

Owing to increased competition, and in some degree to careless harvesting, there was a great fall in prices after 1900, and the Seychellois, though still producing vanilla in large quantities, paid greater attention to the products of the coconut palm - copra, soap, coco-nut oil and coco-nuts - to the development of the mangrove bark industry, the collection of guano, the cultivation of rubber trees, the preparation of banana flour, the growing of sugar canes, and the distillation of rum and essential oils.
Several of the islands contain valuable deposits of guano and phosphate of lime, and their waters are frequented by edible and shell turtle.
